Introduction to the SAS Detail Data Store for Banking Benefits of Implementing the SAS Detail Data Store for Banking 3

What Is the SAS Detail Data Store for Banking? The banking DDS is a data store that serves as the single version of the truth for the SAS Banking Intelligence Solutions. It contains the atomic-level data and historical information that is needed to populate the solution data marts. Figure 1.1 illustrates the high-level role of the SAS Detail Data Store for Banking within the Integrated Solutions Data Architecture.

Figure 1.1 Integrated Solutions Data Architecture

Benefits of Implementing the SAS Detail Data Store for Banking Implementing the banking DDS at a customer site provides several benefits:

The banking DDS provides a single data target for loading data. For example, a customer first implements SAS Credit Risk Management for Banking. During the implementation, the customer populates the Financial_Account table. After the SAS Credit Risk Management for Banking implementation, the customer implements SAS Credit Scoring for Banking. Because the Financial_Account table has already been populated with cleansed data, the customer can use this same table when loading the SAS Credit Scoring for Banking data mart.

4 Industry Versions of the Banking DDS Chapter 1

Because the definition of the banking DDS table is known, the extract, transform, and load (ETL) process from the banking DDS to the solution data marts will be pre-built.

SAS Banking Intelligence Solutions can more easily share system data with each other. For example, the definition of a customer table is the same for SAS Credit Scoring for Banking as it is for SAS Credit Risk Management for Banking. Therefore, populating a single definition of a customer table ensures that both of these solutions have a single version of the truth.

Data that is created from SAS Banking Intelligence Solutions can be stored in a central location and shared with other solutions. For example, the credit scores from SAS Credit Scoring for Banking are written back to the banking DDS and shared with SAS Credit Risk Management for Banking.

Industry Versions of the Banking DDS The banking DDS is part of a larger group of industry data models. Although it would be convenient to have a single data model that covers all industries, in reality, different industries have different data needs. However, as illustrated in Figure 1.2, there is much commonality in data across industries. For example, customer, supplier, product, and segment tables share similar data attributes across industry.

Introduction to the SAS Detail Data Store for Banking Industry Versions of the Banking DDS 5

Figure 1.2 Common Tables across Industry

Data more likely to differ considerably across industry is the customer-facing or front-office data. For example, in banking, there are accounts; in retail, there are transactions; and in insurance, there are premiums and claims. Because of this difference in data, the industry versions of the banking DDS contain tables that are part of the base, cross-industry data model, and contain tables that are part of the industry-specific data model.

6 Industry Versions of the Banking DDS Chapter 1

To further illustrate the concept of sharing data, Figure 1.3 shows a simplified, table-level view of a small section of the banking data model. One set of common tables is in yellow and one set is in dark gray. The base data model (yellow set) was extended by adding some banking-specific tables (dark gray set). This same concept applies to other industry data models, such as insurance, telecommunications, manufacturing, and retail. Having common data allows data models to be easily integrated across industry and functional areas as needed, which is important because companies often operate in multiple industries.

Introduction to the SAS Detail Data Store for Banking Customizing the Banking DDS 7

Customizing the Banking DDS No predesigned data model will meet all of an organization’s needs. Customizations need to be applied to the banking DDS in almost every implementation. For example, Figure1.4 shows how the Competitors table was added to customize the banking DDS. Appendix 7, “Customizing the SAS Detail Data Store for Banking,” provides more information about customizing the banking DDS.

Overview The banking DDS is designed as an integration and storage layer for operational (or source) systems. As such, the banking DDS is a lightly denormalized, relational data model that is flexible for storage. A key difference between a source system and the banking DDS is that the banking DDS captures current and historical data. Capturing historical data includes temporal data history (event data that occurs at a particular date and time, such as an account inquiry) and non-temporal data history (non-event data, such as a customer account or a financial account). Many of the banking DDS design decisions are based on the need for this historical data.

Populating the Retained Key A retained key is a generated surrogate key that uniquely identifies a record at that point in time. Because data is coming from multiple source systems, the business key is not sufficient to identify the record. The retained key (_RK) field, which is part of the primary key, is populated with a retained surrogate (generated) key. This numeric key does not change for the different versions of the record. For example, in the INTERNAL_ORG table in Figure 2.1, the ORGANIZATION_NM column changes from Marketing to World Wide Marketing, but the retained key (shown in the first column) stays as 100. The only change in the old record is in the VALID_TO_DTTM column, which now correctly shows the changed date.

SAS Data Integration Studio has a Slowly Changing Dimension (SCD) transformation, SCD Type2 Loader, which can be used for generating a retained key when the value of an attribute changes in a record.

Tracking Historical Data over Time/Point in Time Data In Figure 2.1, the VALID_FROM_DTTM and VALID_TO_DTTM values are used with the _RK value to track historical data over time. These values define the time period during which the contents of the row are valid. You should set the VALID_TO_DTTM value to a date far into the future for ease of joins. If the source system does not track historical data for records, the VALID_FROM_DTTM and VALID_TO_DTTM values would correspond to the date and time that the DDS was loaded. However, if the source system does track historical data (for example, multiple changes of a row between load times of the DDS), there could be more than one row for the same retained key for a given load of the DDS. The design decision about how the date and time values are managed is related to the deployment of the source system. The date and time values can be tied to business system dates if they are provided by the business system, and if they do not conflict with their primary purpose in tracking the different versions of the system. VALID_FROM_DTTM values can be created from the following:

banking DDS load date and time ETL date and time business system record timestamps

The primary purpose of the VALID_FROM_DTTM and VALID_TO_DTTM values is tracking versions, which is the only use of these values that is guaranteed. If the values are used for another purpose (such as data extract date or business system entry date), then this usage must not compromise the primary purpose.

Physical Design of the SAS Detail Data Store for Banking Using Processed Date/Time 11

Using Effective and Expiration Dates Some types of data have effective and expiration dates that indicate when a business contract or policy is in effect. These date values are different from the date values that are used to track versions. For example, a physical asset’s value remains effective for a certain period of time–the period for which the bank has estimated this value. This estimation changes for future effective and expiration dates for the new versions of the physical asset’s value rows. In Figure 2.2, a bank evaluates the physical asset value of a property on 01MAR2003 that takes effect 01APR2003 (as seen in the EFFECTIVE_FROM_DTTM date, which is the business date). On April 1, 2004, the bank re-evaluates the physical asset value and increases the value, which now supersedes the original value. In Figure 2.2, there are two distinct and valid coverage periods, and a changing business effective period.

31MAR2005 00:00:00

The EFFECTIVE_FROM_DTTM and EFFECTIVE_TO_DTTM values provide effective business periods for the data in this version of the row. If these values do not provide enough historical data with the VALID_FROM_DTTM and VALID_TO_DTTM values, then you can add business-system-related dates, which are subject to naming standards and other standards.

Using Processed Date/Time Knowing the last time that a row was processed in the banking DDS is useful. Processing can include initially creating a row, or updating a row, such as adding the VALID_TO_DTTM value to an existing row. The PROCESSED_DTTM value determines which rows have changed since they were loaded into the data mart by determining the last time that the row was touched by an ETL process or by the data administrator, which includes unusual updates that do not change the row (such as error-correction data-patching).

12 Using Natural/Business Keys Chapter 2

You can populate the PROCESSED_DDTM value by using the Load Time Column option that is available in the SCD Type2 Loader transformation of SAS Data Integration Studio.

Using Natural/Business Keys In the banking DDS, capturing the primary source system identifier (also known as the natural key or business key) and the retained keys in the rows of the tables is useful. The standard for capturing the natural/business key in the banking DDS is <table_name>_ID. Figure 2.3 shows the retained key and natural/business key for a financial account. These natural/business keys originate from the source systems and typically contain long alphanumeric strings. Capturing all keys is useful if you need to go back to the source systems to investigate data.

3 Organization of Tables in the SAS Detail Data Store for Banking

Overview........................................................................................................................................................... 13 More Information ............................................................................................................................................ 17

Overview At a high level, the banking DDS can be grouped into subject areas. In Figure 3.1, the logical data model consists of the following subject areas:

Parties

This subject area includes information on the parties that are involved in banking, such as customers and counterparties. Customer information includes details of individuals, organizations, and corporate customers, associated addresses and contact information, household information for individuals, organization information for corporate customers, and information about the segments to which a household or customer belongs. Counterparty is the opposite party in a bilateral agreement, contract, or transaction. Counterparty information includes details of customers, internal/external organizations, or individuals that are involved in the transactions.

Loss Events

This subject area includes internal loss events and related entities. A loss event is an occurrence of an operational failure, such as a power blackout or computer infrastructure outage. Usually a financial impact is a consequence of a loss event. Loss events are categorized into general risk categories and fall within certain business lines. Loss event data is particularly relevant to operational risk calculation.

Analytics and Scoring

This subject area includes analytical results, such as cross-sell, up-sell, and customer-retention and credit scores, as well as the details of the analytical models. Analytical results are generated by SAS solutions and written to the banking DDS for sharing with other applications.

Financial Accounts

This subject area includes all of the types of financial accounts. The information includes attributes that are common to all financial accounts, such as date opened and account balance. There are also specific types of accounts. These accounts include loan, mortgage, core banking, credit card, investment, life insurance, auto insurance, property insurance, protection insurance, travel insurance, and retirement.

core banking account, including information such as the overdraft charge amount and the interest rate

credit card account, including information such as the payment protection status and the payoff date

retirement account, including information such as the projected retirement age and the tax status

investment account, including information such as the tax withholding information and the dividend frequency

Banking Transactions

This subject area includes transactions that are related to traditional banking accounts, such as withdrawals and deposits. It also includes information that is related to the nature of the transaction such as the transaction amount or the channel of transaction.

Exposures and Risks

This subject area includes the entities that describe the exposure of the financial institution, which include:

liability or financial loss through an account

exposure through financial position holdings

credit that is obtained through a credit facility

Risk Mitigants

This subject area includes the various types of credit risk mitigants that are used to counterbalance exposure. The general types of risk mitigants in the banking DDS are financial and physical assets, credit facilities, guarantees, and receivables.

Products and Instruments

This subject area includes typical retail banking products, such as certificates of deposit, and typical corporate banking products, such as currency swaps. It includes product details, such as product categories and types.

event information, such as address changes, marriage, job changes, which is actively tracked for a customer and available from account management and transactional systems

Insurance Accounts

This subject area includes information about insurance accounts, such as life, travel, auto, property, and protection insurance.

From the context of the banking DDS, insurance coverage assumes that the bank is a third party offering insurance coverage. Details of benefits and adjudication are not stored in the banking DDS.

Insurance Transactions

This subject area includes information about the premiums and claims that are related to the insurance accounts.

Financial Reporting

This subject area includes tables that relate to the financial reporting area of an organization. The financial reporting area contains critical data, including information on annual revenues, net sales revenue, annual interest charges, profit before and after tax, extraordinary income, and other financial measures.

20 Creating the Physical Tables Chapter 4

Install Process Strategy

Creating the Physical Tables DDL CREATE TABLE statements are provided to create the banking DDS physical data structure. A macro named %DDLDDS executes the table definitions by using %INCLUDE statements that reference <tablename>.sas files, which contain the CREATE TABLE statements. The %DDLDDS macro and the <tablename>.sas files are installed on Windows and located at C:\Program Files\SAS\SASBankingDDS\2.5\DDL\SAS. A default DATE9 informat/format is applied to date fields in the %DDLDDS macro. For customer sites with different date requirements, the macro variable DTFMT can be changed to represent the locale (such as EURDFDEw.). The DTFMT macro variable is referenced in the invocation string for the %DDLDDS macro.

Creating and Registering Tables in the SAS Detail Data Store for Banking Importing the Metadata 21

To create the physical tables:

1. Modify and submit the following invocation string: /* Macro variables to be assigned: Fileloc: Assign fileloc macro parameter to point to the directory which contains the DDL create table statements contained in <tablename>.sas files.

DTFMT: (Optional: Defaults to DATE9.) If international date values are needed, assign a new DTFMT= value, such as dtfmt=EURDFDEw.

DTTMFMT: (Optional: Defaults to NLDATM21.) If international datetime values are needed, assign a new DTTMFMT= value, such as dttmfmt=EURDFDTw.

FMTRK: (Optional: Defaults to 12.)*/

NUMW_D: (Optional: Defaults to 18.5) If currency or amount (_amt) fields require a display format, assign a new NUMW_D= value, such as NUMW_D=22.2 to display a width of 22 with 2 decimal places.

TMFMT: (Optional: Defaults to NLTIMAP10.) If time fields are needed to be displayed in a format other than NLTIMAP10., assign TMFMT= value.

%include "<location_of_provided_macro>/ddldds.sas"; LIBNAME DDS “<location_to_store_tables>”; %ddldds(fileloc=<location_of_SAS_DDL>, dttmfmt=<International_Datetime_Value>,dtfmt=<International_ Date_Value>,fmtrk=<default is 12. Use the appropriate length if you made any customizations to the _RK column>);

Your invocation string might look like:

%include "(c:\bankingdds_25_ddl_location\ddldds.sas”); LIBNAME DDS “c:\bankingdds_25\ddl_physical_tables”;

%ddldds(LIBREF=DDS, DTTMFMT=eurdfdt20., TMFMT=NLTIME10., DTFMT=DDMMYY8., FMTRK=10., NUMW_D=15.3, fileloc=”c:\bankingdds_25_ddl_location”);

Note: The %DDLDDS macro code is provided as part of the banking DDS installation, and is located in the Windows default installation folder C:\Program Files\SAS\SASBankingDDS\2.5.

2. Verify that the tables were created correctly by submitting the following code:

proc datasets lib=DDS; quit;

The DATASETS procedure output can be compared with the banking DDS physical data structure.

Importing the Metadata Importing the banking DDS metadata can be performed using either the Import Wizard in SAS Data Integration Studio or the BI Manager plug-in in the SAS Management Console. In this guide, the focus is on using SAS Data Integration Studio to import the banking DDS metadata.

22 Importing the Metadata Chapter 4

There are two other resources that describe how to register metadata using the import feature in SAS Data Integration Studio:

The online Help in the main menu of SAS Data Integration Studio provides information in the “What’s New” section (refer to the section “Enhanced Import and Export of SAS Metadata”). The online Help contains basic information about the import feature in SAS Data Integration Studio.

The “Importing, Exporting, and Copying Metadata” chapter in the SAS Data Integration Studio 3.4: User’s Guide contains detailed information about importing metadata.

Note: If you have installed the banking DDS on a non-Windows platform, ensure that the Windows client on which SAS Data Integration Studio or SAS Management Console is installed has access to the SAS package (.spk) file. Or, you can copy the SAS package file to the local Windows client machine. The SAS package file–bankingdds_25_sas.spk–contains the banking DDS library metadata, custom folder structure, table metadata, table notes metadata, and column notes metadata for the respective data store that are needed for the banking DDS metadata registration. To register your banking DDS metadata using the SAS Data Integration Studio Import Wizard, perform the following steps:

1. Log on as a restricted user to the metadata repository in which you will import the banking DDS metadata using SAS Data Integration Studio. An unrestricted user, such as the Administrator User, cannot be used for the import process.

2. To invoke the Import Wizard, select the Custom tab and expand Repositories Foundation (or Custom) SAS Data Integration Studio Custom Tree. Right-click SAS Data Integration Studio Custom Tree and select Import to invoke the Import Wizard.

3. In the Import Wizard, click Browse to locate the SAS package file, installed on Windows and located at C:\Program Files\SAS\SASBankingDDS\2.5\Metadata\bankingdds_25_sas.spk. Verify that

30 Updating the Metadata Chapter 4

Verification Process Log on to SAS Data Integration Studio to perform verification. The following steps help you verify that the metadata was imported successfully:

Review the log that was produced by the import process. On Windows platforms, logs are written to the user’s folder at a location such as Documents and Settings\<username>\My Documents. The log file is named import_date/time.log.

Select the SAS Data Integration Studio Custom Tree folder and expand the DETAIL_DATA_STORE folder. This folder should contain the following subfolders and their associated metadata: DDS_MAIN (contains the DDS Main tables) DDS_REFERENCE (contains the DDS Reference tables) DDS_NOTES (contains the DDS Table and Column Notes) Detail Data Store library (refers to the banking DDS 2.5 library)

Right-click on Detail Data Store and click Properties. Verify that the library and path specification are correct.

Updating the Metadata If you made any changes to the DDL CREATE TABLE statements, you must update the table metadata to synchronize it with the physical tables. If no changes were made to the DDL CREATE TABLE statements when the physical tables were created, there is no need to update the table metadata. To update the table metadata, log on to SAS Data Integration Studio and select all of the tables that need to be updated from the DDS_MAIN and

Identifying Data Sources Because banks and financial institutions are among the oldest and most mature users of information technology, the number, variety, and application of IT systems are extremely diverse. Quality data must be loaded into the banking DDS to benefit from a SAS Banking Intelligence solution. Therefore, it is critical to identify correct data source systems. Customers with an existing data warehouse can obtain all of the required data from the data warehouse itself. However, other customers might need to obtain data from diverse data source systems, external data stores, and multiple data feeds.

Expected Data Source Systems The following categories of data and IT systems are typical in banks and financial institutions:

customer and account management systems financial account and application management systems collateral management systems marketing and customer intelligence systems product and pricing management systems transactional systems, such as teller systems, ATMs, credit card transaction feeds external data feeds, such as bureau information business and analytical intelligence systems other systems, such as human resources and general ledger

34 Guidelines for Loading Data into the Banking DDS Chapter 5

These categories could be available from a single IT system or from multiple IT systems. Historical information could be available from data archival systems. Or, all of the data could be available in an existing data warehouse.

Guidelines for Loading Data into the Banking DDS After you have identified the banking DDS data sources, you must load the data into the banking DDS. Both the bank or financial institution and the data warehouse consultants need to choose the method to load data into the banking DDS. This choice depends mostly on the structure and diversity of the data source systems. For example, if the number of data source systems is large, and the data source systems are uncoordinated, then consolidating and cleaning data are major considerations. However, if the data source systems are coordinated, or if there is an existing data warehouse, then consolidating and cleaning data are already an integral part of the existing IT system.

Recommended Process The recommended process for loading data into the banking DDS (as shown in Figure 5.1) includes five steps.

Step 1: Define the precise data to be loaded into the banking DDS. The banking DDS is designed to support multiple solutions, although not all of the solutions are implemented simultaneously. Therefore, you must identify the precise data that needs to be loaded into the banking DDS to support the solutions that are to be implemented. This is often an iterative process. A detailed listing of the banking DDS tables and columns that are needed to support specific banking solutions is provided in the Matrix: SAS Detail Data Store for Banking 2.5, Solutions to DDS Mapping spreadsheet. This spreadsheet can be requested from your on-site SAS support personnel. This detailed listing identifies data that needs to be loaded into the banking DDS for a particular SAS solution. The listing might need to be customized based on the specific requirements of the bank or financial institution, or based on the availability of data in the source data systems.

Step 2: Identify and extract the data from the data source systems. Identify the data source systems and the data structures within the data source systems. To accomplish this step, map the banking DDS data to data from the data source systems. For each data source system, a format is defined for the data extract. This format represents how the data is stored in the data source system and optimizes extracting data. Data is extracted from the data source system into an extract file of a defined format.

Loading the SAS Detail Data Store for Banking Guidelines for Loading Data into the Banking DDS 35

Step 3: Clean and consolidate the data from the data source systems. Data that has been extracted from the data source systems and into different formats is cleaned and consolidated into the formats that are suitable for loading the banking DDS. The time that is needed to clean and consolidate the data depends on the condition of the data and the number of data source systems.

Step 4: Load the reference tables. Reference tables that store code values that are required in the banking DDS must be loaded before the banking DDS is loaded because of the following reasons:

Different data source systems might use different codes to represent the same code value.

Codes that are required by the banking DDS might not be defined. The column widths of existing code columns might not match the column widths

that are defined in the banking DDS. Ensure that code values are stored correctly and are available to the solutions that use the banking DDS. As you carefully check the code values for accuracy and availability, include business users, IT staff of the bank or financial institution, and banking solution consultants. After this check is performed, load code manually into the banking DDS reference tables, or extract code from the existing data source systems and load it into the banking DDS reference tables.

Step 5: Load data into the banking DDS and validate. Ensure that data is loaded in the correct sequence. For example, an account transaction cannot be loaded unless the account in which the transaction occurred is first loaded into the banking DDS. Appendix 1, “Table-Loading Sequence,” contains the correct sequence for loading the banking DDS. Because the banking DDS can have data from multiple data source systems, you need to generate the primary key for data in the banking DDS. The column name of the banking DDS primary source identifier has a _RK suffix. The online data dictionary includes details of the primary source identifier (also known as the natural key or business key) for each banking DDS table. When loading data into the banking DDS, the natural key or business key of the source data is matched with data that is available in the banking DDS. If the natural key or business key exists in the banking DDS, the existing banking DDS record is expired, and a new record is inserted with the updated information. The natural key or business key in the banking DDS retains the same value, but the validity dates are changed. If the natural key or business key does not exist in the banking DDS, a new record with a new natural key or business key (calculated as maximum + 1) is inserted.

Note: The business key is typically the primary key from the data source system table and the data source system code. The load time for the banking DDS varies, depending on the volume of data and the number of necessary transformations.

36 Understanding Initial and Periodic Data Loads Chapter 5

Figure 5.1 Loading Data into the Banking DDS

Understanding Initial and Periodic Data Loads The initial data load loads all of the available cleansed, consolidated, and validated data from the data source systems and the associated data archives into the banking DDS. The required history to be loaded depends on the following factors:

the amount of historical data that is available the historical data that is required by the solutions that will be implemented

Loading the SAS Detail Data Store for Banking Archiving Data 37

After the initial data load, the banking DDS and solutions are designed to support any periodic load frequency (daily, weekly, or monthly). The banking DDS and solutions support ad hoc loads and partial loads, as long as the consistency of the data is maintained. For example, an account transaction cannot be loaded unless the account in which the transaction occurred is first loaded into the banking DDS. The actual load frequency depends on a solution’s requirements and the business processes of the bank or financial institution. Periodic loads are generally incremental, and only new or changed data is extracted from the data source systems for loading.

Archiving Data Whether to archive data is based on the answers to the following questions:

How much data can you keep online? When is data no longer needed? What category of data can be archived (for example, transactions or aggregates

only, old customers, old reference data, any data that is older than a certain date)? Is the archived data expected to be reintegrated on short notice? Do you have DBMS-level archival mechanisms, such as partition-level archival or

rollout? What drives archival decisions (for example, space management, regulatory

constraints)? The simplest archival approach with the largest benefit is to archive transactions and aggregates as they age beyond a site-defined threshold. However, you should consider the following facts when you make decisions about archiving.

Associated reference data of a relatively low data volume might be too unimportant.

Age should not be the only factor. For example, an active customer’s record might have been created years ago and have never changed; in this case, you would want to archive the data.

Note: Archiving transactions or aggregates might have an effect on calculated data within the banking DDS, which means the data will have to be recalculated. Archival should be a simple and regularly scheduled task. Test the archival process in a test environment before archiving data from a production environment. In addition, consider the archival-process window, archival tape or disk allocation and storage, recovery procedures, and user notification.

Transactional Tables ...................................................................................................................................... 61 Master Tables .................................................................................................................................................. 61 Reference Tables .............................................................................................................................................. 62 Intersection Tables .......................................................................................................................................... 62 Association Tables ........................................................................................................................................... 62 Supertype and Subtype Tables ....................................................................................................................... 63

Transactional Tables Transactional tables capture events that occur at a particular point in time, or have a beginning and ending time. Examples of transactional tables include:

LOAN_TRANSACTION COMMODITY_QUOTE CUSTOMER_ACCOUNT_SCORE

Master Tables Master tables are reference tables that contain a significant number of rows (for example, over 100 rows) and are frequently updated. Master tables differ from reference tables, which contain a limited number of rows and are relatively static. Master tables typically include the following columns:

an _RK column for a retained key that remains the same for different versions of the same instance of an entity

a VALID_FROM_DTTM column and a VALID_TO_DTTM column that distinguish different versions of the same instance of an entity

an _ID column that identifies the source ID a SOURCE_SYSTEM_CD column for the source system code that identifies where

the _ID column comes from Examples of master tables include the following:

62 Association Tables Appendix 2

Reference Tables Reference tables contain code value definitions. Reference tables are nonvolatile and have a restricted set of values. Reference tables include the following columns:

a _CD column for the code a _DESC column for the code description a VALID_FROM_DTTM column to track changes a VALID_TO_DTTM column to track changes

Examples of reference tables include the following:

ACCOUNT_STATUS ASSET_TYPE

Intersection Tables Intersection tables resolve many-to-many relationships between tables. For example, an employee might be associated with more than one internal organization, and an internal organization contains multiple employees. Examples of intersection tables include the following:

EMPLOYEE_X_INTERNAL_ORG CUSTOMER_X_FINANCIAL_ACCOUNT

Association Tables Association tables establish hierarchy relationships or other relationships between rows in a table. Association tables have an _ASSOC suffix. Association tables include a column that refers to the base rows and a column that refers to the parent row. For example, the INTERNAL_ORG_ASSOC table includes the INTERNAL_ORG_RK column and the PARENT_INTERNAL_ORG_RK column. The INTERNAL_ORG_ASSOC_TYPE_CD column indicates the association type that this row represents. For example, the TYPE code could indicate that the hierarchy is an employee-reporting relationship, such as departments rolling up into divisions. Or, the TYPE code could indicate departments rolling up into different divisions for financial reporting purposes. All association tables have an ASSOC_TYPE table to define the relationship between parent and child rows in the table. Examples of association tables include the following:

INTERNAL_ORG_ASSOC PRODUCT_CATEGORY_ASSOC

Table Types in the SAS Detail Data Store for Banking Supertype and Subtype Tables 63

Supertype and Subtype Tables A supertype table occurs when a parent entity of a category consists of other child entities that exist at a lower level of abstraction and that have their own attributes. For example, CORPORATE_CUSTOMER and INDIVIDUAL_CUSTOMER are subtype tables of the supertype CUSTOMER table. One attribute in the supertype table is used as a category discriminator. This attribute’s value in the physical database indicates which subtype table each record in the supertype table is associated with. A special reference data table stores these values, and contains one record for each value that can be used as a category discriminator. An example of a supertype table and two subtype tables are the following:

CUSTOMER INDIVIDUAL_CUSTOMER CORPORATE_CUSTOMER

3 Standard Data Types and Naming Conventions

The banking DDS data models use a consistent naming convention that includes an abbreviation formula and the use of class codes on the columns, as shown in the table. The class code indicates the type of data that is contained in that field (such as code, indicator flag, and so on). The banking DDS data models use a set of domains to define consistency in data types and lengths.

Reading the Relationship Notation ................................................................................................................ 67 Things to Keep in Mind ........................................................................................................................... 67

Understanding a One-to-One Relationship ................................................................................................... 68 Understanding a One-to-Many Relationship................................................................................................. 68 Understanding a Supertype and Subtype Relationship................................................................................ 69

Reading the Relationship Notation Two tables can have different types of relationships between them. The notation between the tables in the displayed or printed data model indicates how they are related. This appendix describes how to read this notation.

Note: The entire banking DDS data dictionary for the SAS Detail Data Store for Banking is available in the installation package.

Things to Keep in Mind The banking DDS data model uses Information Engineering notation as it is

represented in the Computer Associates AllFusion ERwin Data Modeler. The ellipses indicate that additional columns exist, but that the additional

columns are not necessary to explain the notation. The key sign indicates that the column represents the primary key of the table.

This type of column is needed to uniquely identify rows in the table. For example, EMPLOYEE_ID is the primary key of the EMPLOYEE table.

The letters “FK” indicate that the column serves as the foreign key. A foreign key is a column, or combination of columns, that refers to a primary key in another table. However, in the case of a recursive relationship, a foreign key could refer to a primary key in the same table. For example, DEPARTMENT_ID in the EMPLOYEE table serves as a foreign key in the DEPARTMENT table.

68 Understanding a One-to-Many Relationship Appendix 4

Understanding a One-to-One Relationship The first example illustrates a one-to-one relationship between two tables; the relationship is a non-identifying relationship, which is optional in both directions. The same notation applies when you specify an optional relationship and when you identify relationships in a one-to-one relationship.

Understanding a One-to-Many Relationship The following examples illustrate a one-to-many relationship between a department and an employee. Each department can contain multiple employees; however, subtle differences exist in these relationships. In the first example, an optional relationship exists between a department and employee in both directions. An EMPLOYEE table does not have to have a DEPARTMENT_ID and a DEPARTMENT table does not have to have an EMPLOYEE_ID. This optional relationship is indicated by the circles on both sides.

In the next example, a DEPARTMENT table must contain one or more EMPLOYEE_IDs. This requirement is indicated by the hash mark on the EMPLOYEE side of the relationship.

Page 75: SAS Detail Data Store for Banking 2 - Dartmouth Collegemorgan.dartmouth.edu/Docs/sas92/support.sas.com/documentation/... · The SAS Detail Data Store for Banking 2.5 contains several

Data Model Notation Understanding a Supertype and Subtype Relationship 69

In the next example, the relationship is the same as the previous example, except that an EMPLOYEE table must contain a DEPARTMENT_ID. This requirement is indicated by the hash mark on the DEPARTMENT side of the relationship.

In the next example, an identifying relationship exists between the EMPLOYEE and DEPARTMENT tables. This is indicated by the solid line between the DEPARTMENT table and the EMPLOYEE table. This identifying relationship means that an EMPLOYEE table cannot exist outside the context of a DEPARTMENT table. In identifying relationships, the primary key of the parent table becomes part of the primary key of the child table.

Understanding a Supertype and Subtype Relationship A supertype entity is involved in an inheritance relationship with one or more subtypes. The key attributes or all attributes from this supertype entity can be inherited by each of the subtypes, or the subtype attributes can be consolidated into the parent table. A subtype entity is involved in an inheritance relationship with a parent supertype. The resulting table can inherit attributes from the parent supertype, or attributes can be consolidated with other subtypes into the parent table.

70 Understanding a Supertype and Subtype Relationship Appendix 4

For example, a supertype entity named CUSTOMER has been created to represent the information that is common for different types of customers. The supertype CUSTOMER includes a primary key of customer_id. The subtype entities CORPORATE_CUSTOMER and INDIVIDUAL_CUSTOMER are added as dependent entities that are related to CUSTOMER and contain specific information.

5 Banking DDS FAQ

Question: On what databases can the banking DDS be implemented?

Answer: Out of the box, the banking DDS 2.5 can be implemented on SAS, SAS Scalable Performance Data Server, Oracle, and DB2. Tune the specific databases for optimal performance. For example, add indexes and partitions as needed.

Question: Where is the ERwin file for the banking DDS?

Answer: The ERwin file is not included with the banking DDS. It can be requested through an authorized on-site SAS support personnel.

Question: How do I know what banking DDS data items I need for the solution that I am implementing?

Answer: After installing the banking DDS, a directory named supporting documents is available. In this directory, a .pdf file contains data model diagrams of the SAS solutions that are supported by the banking DDS. In addition, you can request a DDS solutions matrix spreadsheet that maps the banking DDS data items to the various SAS solutions.

Question: How can I determine how the banking DDS data model is organized?

Answer: The .html logical model that is provided with the banking DDS is an excellent resource for understanding how the banking DDS is organized. The logical model provides a high-level subject area model with drill-down capabilities into the entities that comprise each subject area. The logical model is in the logical_model folder.

Question: How is historical data stored in the banking DDS without incrementing the surrogate key value?

Answer: The VALID_FROM_DTTM and VALID_TO_DTTM values are used with the _RK value to track historical data over time. For more details, see the “Tracking Historical Data over Time/Point in Time Data” section in Chapter 2, “Physical Design of the SAS Detail Data Store for Banking.”

Question: How are different hierarchies managed in the banking DDS?

Answer: Hierarchies in the banking DDS are maintained through respective association tables (the ASSOC and ASSOC_TYPE tables). For more details, see the “Association Tables” section in Appendix 2, “Table Types in the SAS Detail Data Store for Banking.”

72 Appendix 5

Question: Is there a hierarchy for the FINANCIAL_UNIT table?

Answer: No. The FINANCIAL_UNIT table has a relationship with either the INTERNAL_ORG or EXTERNAL_ORG table, and its hierarchy is available through the respective ASSOC and ASSOC_TYPE tables on the ORG tables.

Question: In the banking DDS, the FINANCIAL_PRODUCT_ACCOUNT table that shows the product and account relationship is not in the history. It has no VALID_FROM and VALID_TO attributes. In this case, how can I handle history? How can I see which product was associated to the account two years ago? Should it be managed by the start and end dates? If yes, how can it be populated? Should we use the SCD Type2 Loader as well?

Answer: For the FINANCIAL_PRODUCT_ACCOUNT table, you can use START_DT and END_DT (part of the primary key in this table) for maintaining history. Verify that the SCD Type2 Loader options use DATE as a means of tracking history, instead of DATETIME.

Question: What is the proper use of EFFECTIVE_FROM_DTTM and EFFECTIVE_TO_DTTM, versus VALID_FROM_DTTM and VALID_TO_DTTM?

Answer: VALID_FROM_DTTM and VALID_TO_DTTM handle the SCD Type2 attributes in a particular row and indicate which record is valid for a given time period. EFFECTIVE_FROM_DTTM and EFFECTIVE_TO_DTTM represent the business date that is associated with the row and can remain constant for multiple rows for a given attribute. For example, an analytical model might be designed to be effective for a certain period of time (for example, a future date). That effective period of time might end at a certain date. However, even if the analytical model is no longer in effect, the data itself is still valid.

Question: Why does the banking DDS specify Numeric(18,5) for currency amounts?

Answer: The banking DDS typically uses Numeric(18,5) as the specification for currency amounts. However, if the banking DDS is implemented in SAS, the upper limit on the floating-point precision is 15 decimal places. Although this could lead to a loss of decimal-place precision, the likelihood of this issue being encountered at a customer site is low. Should this issue occur, you could limit the input to a width of 15 with a precision of 3 decimal places – Informat(15,3). Because you would lose decimal-place precision, this solution should be weighed against the likelihood of encountering a problem with the data that is being loaded into the banking DDS.

6 Defining Role-Based Users and Groups for the Banking DDS

Overview........................................................................................................................................................... 73 Planning User Groups and Roles ................................................................................................................... 73 Sample User Groups and Roles ...................................................................................................................... 74

Metadata Administrator ......................................................................................................................... 75 DDS Administrator ................................................................................................................................. 75 ETL Administrator.................................................................................................................................. 75 Information Architect .............................................................................................................................. 75 Power Users.............................................................................................................................................. 76

Overview The tasks in this appendix describe how to define metadata user roles, set up appropriate user IDs, and assign user IDs to groups. This appendix provides a recommended role-based setup guide for banking DDS metadata users. Although the appendix provides recommendations on potential roles, each business should define its own roles that are based on the specialized functions that are required by the business.

Planning User Groups and Roles The steps in planning user groups and roles are:

1 Define user roles that are based on business and functional needs.

2 Determine which user accounts you must establish in the metadata for the business and functional needs.

3 Decide how to organize users into groups.

When setting up user roles, analyze the business and functional needs that pertain to the banking DDS setup and usage. User roles should be robust for the administrative roles, and limited, but not limiting, for the power user roles. User roles should have the correct balance between deployability, usability, and maintainability for your metadata. Consider the various business and functional tasks that need to be accomplished to set up the proper user environment for the banking DDS. For example, some required business and functional tasks are:

setting up the SAS Metadata Server environment registering and administering the metadata maintaining, scheduling, and running the ETL jobs

74 Sample User Groups and Roles Appendix 6

creating information maps creating, running, and viewing reports

After defining the business and functional tasks, create the user IDs and permissions that are necessary to perform the tasks. It is a best practice to organize users into groups because it simplifies the process of establishing and managing the users. Assigning permissions to users on an individual basis can be cumbersome. After defining the groups, assign permissions to the groups rather than to individual users.

Note: Two user groups are automatically created in the Foundation repository: PUBLIC and SASUSERS. Membership in the PUBLIC and SASUSERS groups is implicit. If you can access the SAS Metadata Server, then you are automatically a member of the PUBLIC group. If you can access the SAS Metadata Server and you have your own metadata identity, then you are automatically a member of both the PUBLIC group and the SASUSERS group. Define the user roles and create the groups that are necessary to assist with the administration of the banking DDS.

Sample User Groups and Roles This section suggests user roles and groups. There are various other ways to establish metadata user IDs. For example, there could be a developer group and many types of power users. The sample user roles are derived from the perspective of a production environment. Metadata Administrator

This role is the unrestricted user. It acts as overall administrator for the metadata repository. It is not given access to the directories that contain data.

DDS Administrator This role is the administrator for the banking DDS. It is responsible for managing the metadata for the banking DDS and owns directories that contain banking DDS and any other critical customer data.

ETL Administrator This role updates and runs ETL jobs and provides production support.

Information Architect This role creates information maps using the banking DDS data files. It coordinates with the DDS Administrator to set up privileges for Power Users.

Power Users This role queries the information maps that have been set up. Access to the information maps is assigned by the DDS Administrator in consultation with the Information Architect.

Users and groups are defined around these functional tasks and user roles.

Defining Role-Based Users and Groups for the Banking DDS Sample User Groups and Roles 75

Metadata Administrator The Metadata Administrator is the unrestricted user for your SAS installation. For a default SAS installation, this user is sasadm. This user has unrestricted privileges to the Foundation repository and can make changes to the SAS installation. The Metadata Administrator is responsible for the following:

installing the SAS Metadata Server and other SAS software setting up scripts and services to start and stop the servers creating the Foundation repository setting up and registering the servers within the Foundation repository creating administrative users (for example, the DDS Administrator)

DDS Administrator The DDS Administrator deploys the banking DDS and ETL jobs. The DDS Administrator is created by the Metadata Administrator. The DDS Administrator is responsible for the following:

creating the banking DDS physical data files creating the library and registering the banking DDS metadata creating other libraries that are needed by the deployment importing ETL jobs and EFI (External File Interface) objects creating other users and groups, such as the ETL Administrator and Power Users assigning permissions to the user accounts creating deployment directories

ETL Administrator The ETL Administrator develops, schedules, manages, and deploys ETL jobs. The ETL Administrator is responsible for the following:

verifying that production deployment has worked properly deploying ETL jobs making changes to ETL jobs using SAS Data Integration Studio scheduling ETL jobs using LSF Scheduler or any other third-party scheduler providing production support to resolve any problems in the data reporting on job status by directly accessing the data sets that are created for this

purpose

Information Architect The Information Architect designs, creates, and deploys information maps for Power Users using SAS Information Map Studio. The Information Architect is responsible for the following:

creating and maintaining information maps working with DDS Administrators to set up privileges for Power Users

76 Sample User Groups and Roles Appendix 6

Power Users The Power Users consume the information maps that are generated by the Information Architects. Power Users query the banking DDS based on the information maps. There can be many types of power users. You might need different groups of power users to focus on different business areas. For example, you might set up a credit card power user to focus on credit card accounts, and an investment power user to focus on investment information. Access for power users is restricted to the information maps that they need. The Power User is responsible for the following:

running information maps that have been assigned to the Power User working with the Information Architect to update or request information maps

Overview........................................................................................................................................................... 77 Supported Customizations.............................................................................................................................. 78 Types of Customizations.................................................................................................................................. 78 Scope of Customizations.................................................................................................................................. 79 Steps for Customization .................................................................................................................................. 80 Modifying the Banking DDS .......................................................................................................................... 80 Using Caution.................................................................................................................................................. 81 Avoiding Trouble ............................................................................................................................................. 81 Things to Keep in Mind................................................................................................................................... 81 Tracking Customizations ................................................................................................................................ 82

Overview Initially, the scope of the banking DDS can be larger than the scope of the data that is to be subsequently loaded. New data might be required or a new SAS solution might be needed that requires data that was not previously loaded into the banking DDS. You might need to populate tables and fields in the banking DDS that exist, but were not previously required. An issue to consider is time consistency. If new data will not be loaded to the same historical point in time as the current banking DDS, then that fact must be known to the application that is accessing the data. New data table, column, or field-level requirements mean the following:

a change to data source system extract files a change to SAS Data Integration Studio jobs a possible change to dependencies, DDS tables, and indices the need for new SAS Data Integration Studio jobs for downstream applications

(for example, the solution’s applications that created the new data requirements) Understanding the data flow from the data source to the banking DDS means understanding the impact of adding new data requirements. Identify each affected component, starting with data source system extract files, and modify each component accordingly in a test environment. All customizations should follow the customization guidelines, and all additions should have a defined prefix (for example, X_), which ensures that the upgraded version of the banking DDS does not have a table or column of the same name. Additions should have a meaningful and accurate description.

78 Types of Customizations Appendix 7

Supported Customizations Adding Tables You can add tables to support a new business area or to enhance the functionality of an existing business area that is not in the current banking DDS. New tables should be added with a prefix (for example, X_) to distinguish them from tables that are provided in the current banking DDS. Adding Columns You can add columns to existing tables in the banking DDS to support a new business area or to enhance the functionality of an existing business area that is not in the current banking DDS. New columns should be added with a prefix (for example, X_) to distinguish them from columns that are provided in the current banking DDS. Expanding Column Length You can expand the column length to accommodate the data from upstream applications. You should perform an impact analysis before expanding the length of a column to avoid truncation in tables in downstream applications. Changing Formats and Informats You can change the formats and informats to address the local language requirements. Storing Descriptions in Different Languages Reference tables allow descriptions to be stored in multiple languages. Use the LANGUAGE_CD column in the reference table to specify the language for the description. Remember the downstream processing impact if you store a description in more than one language.

Types of Customizations Customizations can be classified as:

Simple changes: No effect on data structure, logic, or process in the data warehouse (for example, character column length increase, label or format for a column, extra descriptive columns not referenced by supplied applications)

Moderate changes: Localized and clear and simple effect on data structure, logic, or process in the data warehouse (for example, extra data columns for a few specific tables)

Complex changes: Widespread effect with potential complex impact on data structure, logic, or process in the data warehouse (for example, addition of a new table)

The degree of complexity is based on how much manual effort is required and how many components are affected. You should avoid making complex changes because they add to the cost and make future upgrades more difficult.

Cascading effects should be considered when deciding whether to build a new data structure or modify an existing one. Based on the figure, the following areas are candidates for customization: Data Model Customization

Detail Data Store Data Delivery ETL Process Customization Reporting Customization

Information Maps Report Definitions

Data Management Processes

Note: Only guidelines for the banking DDS are covered in this document. For guidelines for other business subject areas, refer to the customization guidelines of the respective solutions.

80 Modifying the Banking DDS Appendix 7

Steps for Customization Customizations should be performed by taking a step-by-step approach. Step 1: Identify the customization requirements.

a. Identify the gaps between requirements and the solution’s predefined data mart.

b. For each additional variable that is required in the target data mart, determine whether the required data is available in the banking DDS.

Note: In certain cases, the gaps might not be apparent. If aggregated or derived variables are available in source systems or existing data warehouses, the variables might be directly added to the banking DDS tables to avoid duplicating business rules or aggregations in solutions. Step 2: Map the requirements to identify the banking DDS customizations. Based on the banking DDS gap analysis, specific additions to the banking DDS are identified in this step.

a. First, identify the columns that need to be added to the existing tables.

b. In case the gaps between requirements and the solution are not filled by adding new columns, identify additional tables that need to be added to fill gaps. Also, identify the relationships of the new tables with the existing tables.

Step 3: Implement the identified customizations.

Note: Any changes that are made to the predefined banking DDS environment should be logged. Details of tracking changes are mentioned in a subsequent section.

Modifying the Banking DDS Typically, you can expect to make the following modifications during an implementation:

adding local language or value format requirements adding columns in the tables because of business requirements adding an entity or table because of a new area of business adding new data formats customizing the language code (LANGUAGE_CD) to be specific to a country customizing most of the amount values that use currencies (CURRENCY_CD) to

be specific to a country changing column labels (without any impact) expanding column lengths when data is expected to be longer

This will not have any impact on existing data, but processes that refer to a column whose length has been expanded will need to be updated.

Customizing the SAS Detail Data Store for Banking Things to Keep in Mind 81

Using Caution You can add columns to tables; however, if you use these columns in downstream

applications that have already been implemented, you will need to customize the downstream applications.

You cannot reduce the length of columns because doing so might impact downstream processing.

You can expand the length of columns; however, do so carefully because this can lead to truncation at the solution level.

You can add tables; however, if you use these tables in downstream applications that have already been implemented, you will need to customize the downstream applications. If you add a new business subject area, you should add new processes instead of modifying existing processes.

Avoiding Trouble Do not change column names because doing so can significantly impact

downstream applications that have already been implemented. Do not change data types for columns because doing so can significantly impact

downstream applications that have already been implemented. Do not delete columns. Columns that are not required by the client can hold

missing values. Do not reduce the length of columns because doing so can significantly impact

downstream processing.

Things to Keep in Mind Develop and test modifications to the banking DDS in a controlled development or

test environment before you migrate the modifications to a production environment.

You can add tables or columns or modify the length of columns within the SAS Data Integration Studio environment. See the SAS Data Integration Studio: User’s Guide for more information.

If you change the provided DDL files, back up or copy the original DDL files in case you need to get back to a known starting point.

Identify the job dependencies and job order for new jobs and schedule the jobs accordingly.

When creating user-defined tables and columns, include meaningful and accurate descriptions that are clear and concise without circular reasoning.

8 Deploying the SAS Detail Data Store for Banking in SAS Scalable Performance Data Server

Overview........................................................................................................................................................... 83 Prerequisites .................................................................................................................................................... 83 Creating the Physical Tables .......................................................................................................................... 84 Importing the Metadata .................................................................................................................................. 85 Verification Process ......................................................................................................................................... 95 Updating the Metadata................................................................................................................................... 95

Overview This appendix describes how to set up the SAS Detail Data Store for Banking in a SAS Scalable Performance Data Server environment. It provides step-by-step instructions to help the on-site SAS support personnel and customer system administrator create the physical tables and to register the metadata in an existing metadata repository.

Note: The instructions in this appendix have been tested on a Windows NT 5.2 Service Pack 1 machine with a SAS Scalable Performance Data Server 4.4 client and on a Windows NT 5.2 Service Pack 1 server machine with an SAS Scalable Performance Data Server 4.4 server.

Prerequisites

SAS Scalable Performance Data Server environment deployment requires the SAS Scalable Performance Data Server DDL and the SAS Scalable Performance Data Server package file.

The SAS Scalable Performance Data Server client must be properly installed with access to a server environment in SAS Scalable Performance Data Server.

SAS Data Integration Studio 3.4 or later must be installed and functional. Many administrative tasks, such as setting up the servers that are used to execute jobs, are performed outside of the SAS Data Integration Studio interface. Such administrative tasks are described in the SAS Intelligence Platform documentation, which can be found at http://support.sas.com/913administration. These tasks are required before loading some of the components of the banking DDS. Additionally, all SAS Data Integration Studio hot fixes should be applied. Hot fixes can be downloaded from http://support.sas.com/techsup.

84 Creating the Physical Tables Appendix 8

A SAS Metadata Server and a metadata repository must be operational. Connectivity to the server in SAS Scalable Performance Data Server must be set up in the Foundation repository in which the banking DDS metadata will be registered.

Contact the metadata administrator for the SAS Intelligence Platform to request the server name in SAS Scalable Performance Data Server in the metadata repository. SAS Scalable Performance Data Server connectivity is explained in the “Connecting to Common Data Sources” section in SAS 9.1.3 Intelligence Platform: Data Administration Guide. The SAS Data Integration Studio user ID must be set up for the Authentication Domain of the server.

The server name and schema in SAS Scalable Performance Data Server must exist for the SAS Scalable Performance Data Server package file import process during the metadata registration process.

Creating the Physical Tables DDL CREATE TABLE statements are provided to create the banking DDS physical data structure. A macro named %SPDDLDDS executes the table definitions by using %INCLUDE statements that reference <tablename>.sas files, which contain the CREATE TABLE statements. A default DATE9 informat/format is applied to date fields in the %SPDDLDDS macro. For customer sites with different date requirements, the macro variable DTFMT can be changed to represent the locale (such as EURDFDEw.). The DTFMT macro variable is referenced in the invocation string for the %SPDDLDDS macro. To create the physical tables:

1. Set up the DDS LIBNAME using the SAS Scalable Performance Data Server library engine.

LIBNAME DDS SASSPDS ’<SPDS-data-library>’ SERVER=’<node_name.servname>’ USER=’<user_id>’ PASSWORD=’Password’;

For example, suppose your server LIBNAME domain is spdslib, the SAS Scalable Performance Data Server host machine is spdhost, the SAS Scalable Performance Data Server user ID is user1, the password is Pass1, and the SAS Scalable Performance Data Server named service is spdsname. Your LIBNAME statement would look like the following:

LIBNAME DDS SASSPDS ’spdslib’ SERVER=’spdhost.spdsname’ user=’user1’ password=’Pass1’;

2. Modify and submit the following invocation string:

/* Macro variables to be assigned: Fileloc: Assign fileloc macro parameter to point to the directory which contains the DDL create table statements contained in <tablename>.sas files.

DTFMT: (Optional: Defaults to DATE9.) If international date values are needed, assign a new DTFMT= value, such as dtfmt=EURDFDEw.

DTTMFMT: (Optional: Defaults to NLDATM21.) If international datetime values are needed, assign a new DTTMFMT= value, such as dttmfmt=EURDFDTw.

FMTRK: (Optional: Defaults to 12.) Assign a display format for retained surrogate keys such as fmtrk=10.

Deploying the SAS Detail Data Store for Banking in SAS Scalable Performance Data Server Importing the Metadata 85

NUMW_D: (Optional: Defaults to 18.5 If currency or amount (_amt) fields require a display format, assign a new NUMW_D= value, such as NUMW_D=22.2 to display width of 22 with 2 decimal places.

TMFMT: (Optional: Defaults to: NLTIMAP10.) If Time fields are needed to be displayed in a format other than NLTIMAP10., assign TMFMT= value.

%include "<location_of_provided_macro>/spddldds.sas";

LIBNAME DDS “<location_to_store_tables>”;

%spddldds(USER=,PASS=,PATH=,fileloc=<location_of_SPDS_DDL_folder>),

dtfmt=<International_Date_Value>, fmtrk=<default is 12. Use the

appropriate length if you made any customizations to the _RK column>);

%include "<location_of_provided_macro>/spddldds.sas"; %spddldds(USER=,PASS=,PATH=,fileloc=<location_of_SPDS_DDL_folder>);

*/

Note: When invoking the %SPDDDLDDS macro, the FILELOC macro variable has to be set to the folder where the SPDS DDL files are located. For example, if the SPDS DDL files are located in the C:\BankingDDS\DDL\SPDS folder, then FILELOC has to be set to C:\BankingDDS\DDL. For example, using the previous settings, the macro invocation code would look like this:

%include “C:\BankingDDS\DDL\SPDS\spddldds.sas”;

%spddldds(fileloc= C:\BankingDDS\DDL);

3. Verify that the tables were created correctly by submitting the following code:

proc datasets lib=DDS; quit;

The DATASETS procedure output can be compared with the banking DDS physical data structure.

Importing the Metadata Importing the banking DDS metadata can be performed using either the Import Wizard in SAS Data Integration Studio or the BI Manager plug-in in the SAS Management Console. In this guide, the focus is on using SAS Data Integration Studio to import banking DDS metadata. There are two other resources that describe how to register metadata using the import feature in SAS Data Integration Studio:

The online Help in the main menu of SAS Data Integration Studio provides information in the “What’s New” section (refer to the section “Enhanced Import and Export of SAS Metadata”). The online Help contains basic information about the import feature in SAS Data Integration Studio.

The “Importing, Exporting, and Copying Metadata” chapter in the SAS Data Integration Studio 3.4 User’s Guide contains detailed information about importing metadata.

86 Importing the Metadata Appendix 8

The SAS package file for SAS Scalable Performance Data Server–bankingdds_25_spds.spk–contains the banking DDS library metadata, custom folder structure, table metadata, table notes metadata, and column notes metadata that are needed for the banking DDS metadata registration.

Note: If you have installed the banking DDS on a non-Windows platform, the Windows clients such as SAS Data Integration Studio and SAS Management Console require access to the package files. Accessing the UNIX file system from Windows, or transferring these files from the UNIX file system to the Windows file system, is necessary because these files are required as input to the Windows-based clients. To register your banking DDS metadata using the SAS Data Integration Studio Import Wizard, perform the following steps:

1. Log on as a restricted user to the metadata repository in which you will import the banking DDS metadata using SAS Data Integration Studio. An unrestricted user, such as the Administrator User, cannot be used for the import process.

2. To invoke the Import Wizard, select the Custom tab and expand Repositories Foundation (or Custom) SAS Data Integration Studio Custom Tree. Right-click SAS Data Integration Studio Custom Tree and select Import to invoke the Import Wizard.

A macro named %ORDDLDDS executes the table definitions by using %INCLUDE statements that reference <tablename>.sas files, which contain the CREATE TABLE statements. The %ORDDLDDS macro and the <tablename>.sas files are installed on Windows and located at the default install location of C:\Program Files\SAS\SASBankingDDS\2.5\DDL\Oracle. A default DATE9 informat/format is applied to date fields in the %ORDDLDDS macro. For customer sites with different date requirements, the macro variable DTFMT can be changed to represent the locale (such as EURDFDEw.). The DTFMT macro variable is referenced in the invocation string for the %ORDDLDDS macro. To create the physical tables:

1. Set up the DDS LIBNAME using the Oracle library engine.

LIBNAME DDS ORACLE PATH=’<Oracle TNS Entry>’ USER=’<user name>’ PASSWORD=’<Password>’;

For example, suppose your Oracle user ID is scott, the password is tiger, and the Oracle TNS network configuration points to bankdb.acme.com. Your LIBNAME statement would look like the following:

LIBNAME DDS ORACLE PATH=’bankdb.acme.com’ USER=’scott’ PASSWORD=’tiger’;

2. Modify and submit the following invocation string:

/* Macro variables to be assigned: Fileloc: Assign fileloc macro parameter to point to the directory which contains the DDL create table statements contained in <tablename>.sas files.

DTFMT: (Optional: Defaults to DATE9.) If international date values are needed, assign a new DTFMT= value, such as dtfmt=EURDFDEw.

DTTMFMT: (Optional: Defaults to NLDATM21.) If international datetime values are needed, assign a new DTTMFMT= value, such as dttmfmt=EURDFDTw.

FMTRK: (Optional: Defaults to 12.) Assign a display format for retained surrogate keys such as fmtrk=10.

NUMW_D: (Optional: Defaults to 18.5 If currency or amount (_amt) fields require a display format, assign a new NUMW_D= value, such as NUMW_D=22.2 to display width of 22 with 2 decimal places.

TMFMT: (Optional: Defaults to: NLTIMAP10.) If Time fields are needed to be displayed in a format other than NLTIMAP10., assign TMFMT= value.

%include ‘<location_of_provided_macro>/orddldds.sas’;

*/

Note: When invoking the %ORDDLDDS macro, the FILELOC macro variable has to be set to the folder where the Oracle DDL files are located. For example, if the Oracle DDL files are located in the Windows install folder location of C:\Program Files\SAS\SASBankingDDS\2.5\DDL\Oracle, then FILELOC has to be set to this folder location. For example, using the previous settings, the macro invocation code would look like this:

%include “C:\Program Files\SAS\SASBankingDDS\2.5\DDL\Oracle \orddldds.sas”;

%orddldds(USER=’scott’,PASS=’tiger’,PATH=’bankdb.acme.com’,fileloc= C:\Program Files\SAS\SASBankingDDS\2.5\DDL\Oracle);

3. Verify that the tables were created correctly by submitting the following code:

proc datasets lib=DDS; quit;

The DATASETS procedure output can be compared with the banking DDS physical data structure.

Importing the Metadata Importing the banking DDS metadata can be performed using either the Import Wizard in SAS Data Integration Studio or the BI Manager plug-in in the SAS Management Console. In this guide, the focus is on using SAS Data Integration Studio to import banking DDS metadata. There are two other resources that describe how to register metadata using the import feature in SAS Data Integration Studio:

The online Help in the main menu of SAS Data Integration Studio provides information in the “What’s New” section (refer to the section “Enhanced Import and Export of SAS Metadata”). The online Help contains basic information about the import feature in SAS Data Integration Studio.

The “Importing, Exporting, and Copying Metadata” chapter in the SAS Data Integration Studio 3.4 User’s Guide contains detailed information about importing metadata.

The SAS package file for Oracle–bankingdds_25_oracle.spk–contains the banking DDS library metadata, custom folder structure, table metadata, table notes metadata, and column notes metadata that are needed for the banking DDS metadata registration. To register your banking DDS metadata using the SAS Data Integration Studio Import Wizard, perform the following steps:

1. Log on as a restricted user to the metadata repository in which you will import the banking DDS metadata using SAS Data Integration Studio. An unrestricted user, such as the Administrator User, cannot be used for the import process.

Overview This appendix describes how to set up the SAS Detail Data Store for Banking in a DB2 environment. It provides step-by-step instructions to help the on-site SAS support personnel and customer system administrator create the physical tables and to register the metadata in an existing metadata repository.

Note: The instructions in this appendix have been tested on a Windows XP Service Pack 2 machine with a DB2 9.1 client, and on a Windows 2000 Service Pack 4 server machine with a DB2 9.1.0.0 database.

Prerequisites

DB2 environment deployment requires the DB2 DDL and the DB2 package file. SAS/ACCESS Interface to DB2 must be installed. For more information on DB2

installations, see “Connecting to Common Data Sources,” in the SAS Intelligence Plaform: Data Administration Guide.

DB2 clients must be installed and available for accessing the DB2 tables. SAS Data Integration Studio 3.4 or later must be installed and functional. Many

administrative tasks, such as setting up the servers that are used to execute jobs, are performed outside of the SAS Data Integration Studio interface. Such administrative tasks are described in the SAS Intelligence Platform documentation, which can be found at http://support.sas.com/913administration. These tasks are required before loading some of the components of the banking DDS. Additionally, all SAS Data Integration Studio hot fixes should be applied. Hot fixes can be downloaded from http://support.sas.com/techsup.

A SAS Metadata Server and a metadata repository must be operational. Connectivity to the DB2 server must be set up in the Foundation repository in which the banking DDS metadata will be registered.

114 Creating the Physical Tables Appendix 10

The server name and schema in DB2 must exist for the DB2 package file import process during the metadata registration process.

Creating the Physical Tables DDL CREATE TABLE statements are provided to create the banking DDS physical data structure. A macro named %D2DDLDDS executes the table definitions by using %INCLUDE statements that reference <tablename>.sas files, which contain the CREATE TABLE statements. The %D2DDLDDS macro and the <tablename>.sas files are installed on Windows and located at the default install location of C:\Program Files\SAS\SASBankingDDS\2.5\DDL\DB2. A default DATE9 informat/format is applied to date fields in the %D2DDLDDS macro. For customer sites with different date requirements, the macro variable DTFMT can be changed to represent the locale (such as EURDFDEw.). The DTFMT macro variable is referenced in the invocation string for the %D2DDLDDS macro. To create the physical tables:

1. Set up the DDS LIBNAME using the DB2 library engine.

LIBNAME DDS DB2 DSN=’<DB2 Data Server Name>’ USER=’<user name>’ PASSWORD=’<Password>’ SCHEMA=’<schema name>’;

For example, suppose your DB2 user ID is dba1, the password is Pass1, the DSN is sample, and the schema is BANKINGDDS. Your LIBNAME statement would look like the following:

LIBNAME DDS DB2 DSN=’sample’ USER=’dba1’ PASSWORD=’Pass1’ schema=BANKINGDDS;

2. Modify and submit the following invocation string:

/* Macro variables to be assigned: Fileloc: Assign fileloc macro parameter to point to the directory which contains the DDL create table statements contained in <tablename>.sas files.

DTFMT: (Optional: Defaults to DATE9.) If international date values are needed, assign a new DTFMT= value, such as dtfmt=EURDFDEw.

DTTMFMT: (Optional: Defaults to NLDATM21.) If international datetime values are needed, assign a new DTTMFMT= value, such as dttmfmt=EURDFDTw.

FMTRK: (Optional: Defaults to 12.) Assign a display format for retained surrogate keys such as fmtrk=10.

NUMW_D: (Optional: Defaults to 18.5 If currency or amount (_amt) fields require a display format, assign a new NUMW_D= value, such as NUMW_D=22.2 to display width of 22 with 2 decimal places

TMFMT: (Optional: Defaults to: NLTIMAP10.) If Time fields are needed to be displayed in a format other than NLTIMAP10., assign TMFMT= value.

physical data model represents the detailed specifications of what is physically implemented as data

objects such as tables, views, and so on.

primary key a set of one or more attributes that uniquely identifies a single occurrence in a data

structure, such as a row in a table. In a logical model, every entity has a primary key.

reference table contains the code value definitions and their associated descriptions. A reference

table is non-volatile (rarely updated) and has a restricted set of values.

relationship an important, real-world association among entities that has meaning as business

information. In a subject model, relationships illustrate the most visible business associations among subjects. In a physical data model, relationships are implemented via foreign keys. For example, the relationship "a customer can open one or more accounts" is implemented by placing the customer primary key as a foreign key on all financial account records for that customer.

retained key a generated surrogate key that uniquely identifies a record at that point in time.

Because data is coming from multiple source systems, the business key is not sufficient to identify the record. The retained key (_RK) field, which is part of the primary key, is populated with a retained surrogate (generated) key. This numeric key does not change for the different versions of the record.

130 Glossary

slowly changing dimension (SCD) a technique for tracking changes to table values in order to maintain the history of

changes. For example, a dimension table named Customers might have columns for Customer ID, Home Address, Age, and Income. Each time the address or income changes for a customer, a new row could be created for that customer in the dimension table, and the old row could be retained. This historical record of changes could be combined with purchasing information to forecast buying trends and to direct customer marketing campaigns.

source an input to an operation. Source is often referred to as source data.

source system identifier See business key or natural key.

subject a high-level view of a topic of business interest that is equivalent to both a global

data class and a class of data entities.

subtype an entity or table that is involved in an inheritance relationship with a parent

supertype. The resulting table can inherit attributes from the parent supertype, or attributes can be consolidated with other subtypes into the parent table.

surrogate key a single-part, artificially established identifier for an entity. A surrogate key is a

special case of derived data - one where the primary key is derived. A common way of deriving surrogate key values is to assign integer values sequentially.

supertype an entity that is involved in an inheritance relationship with one or more subtypes.

The key attributes or all attributes from this supertype entity can be inherited by each of the subtypes, or the subtype attributes can be consolidated into the parent table.

target an output location of an operation.

temporal data event data that occurs at a particular date and time, such as an account inquiry.

Temporal data is often referred to as time-sensitive data.

transformation a process that performs some type of transformation on data in SAS Data

Integration Studio. Each transformation that is specified in a process flow diagram generates or retrieves SAS code. User-written code can be specified in the metadata for any transformation in the process flow diagram.
