•Packaged set of ETL mappings, dimensional data warehouse and pre-built reports anddashboards

•Financial Analytics

•HR Analytics

•

Marketing Analytics•Order Management Analytics

•Contact Center Analytics

•Supply Chain Analytics




Oracle BI Applications Core Proposition : Financial Analytics






Part of Oracle Business Intelligence Technology Stack






Estimated 5x Development Productivity Boost






Prebuilt Dashboards and Reports






Prebuilt OBIEE Repository






The Oracle BI Applications Business Model & Mapping Layer

•The Business Model and Mapping layer contains the complete, integrated logicaldata model for the OBAW

•Divided in to core and application-specificbusiness models

•Coverage of the business model isdetermined by the products selectedat installation time




DemonstrationThe OBIEE Repository with Oracle BI Applications Data Items




Oracle BI Applications Architecture






Predefined, Integrated Dimensional Data Warehouse

• Integrated, conformed dimensional data warehouse

•Allows modular deployment

• Lowest grain of information

•Prebuilt aggregates

•

Deployable on Oracle, MS SQL,IBM DB/2 and Teradata

•History tracking

• Indexing




The Oracle BI Applications ETL Process

•Oracle BI Applications comes with a set of pre-defined ETL routines

‣Currently written using Informatica, in future also provided via Oracle DI

•Extracts data from Oracle EBS, Peoplesoft, Siebel, SAP

•Universal Adapter available for non-supported sources

•

Controlled and orchestrated using the Oracle Data Warehouse Administration Console




Oracle Data Warehouse Administration Console

•Control panel for running the OBAW load process

•ETL packaged into Execution Plans

•Tight integration with Informatica

•Run jobs, monitor progress

•

The added value on top of the OBAW and INFA mappings




DemonstrationThe Oracle Data Warehouse Administration Console




Informatica PowerCenter 8.1.1

• Informatica PowerCenter 8.1.1 is a complete ETL toolkit

‣Very much like Oracle Warehouse Builder, but applies to all sources and targets

‣Uses an ETL “hub” toprocess and distribute data

•

Server supported on Windows,Unix, Linux

•Client is Windows-only

•Five Key Informatica Client Tools

‣ Informatica Designer

‣ Informatica Workflow Manager

‣ Informatica Repository Manager ‣ Informatica Workflow Monitor




Oracle Data Integrator

•A future release of the Oracle BI Applications will support ODI as the ETL tool

‣ Initially EBS to Oracle only, future releases will support all sources/targets

•Oracle heterogeneous ETL tool

•Acquired through Sunopsis Acquisition

•

ELT approach•Part of Oracle Fusion Middleware

•Customers can adopt either Informatica or ODI, Informatica willcontinue to be supported




Customizing the Oracle Business Analytics Warehouse

•Although the OBAW comes with many star schemas and many ETL routines, you willprobably wish to extend and customize it to meet your neds

‣ Include flex-field data

‣Adding data from a custom source

‣

Adding new facts, dimensions, hierarchies

•Data can come from many sources

‣Sources with adapters and existing load routines you can customize

‣Sources with adapters but no load routines (source unsupported for subject area)

‣Unsupported sources (using the Universal Adapter)




Customizing and Creating New OBAW ETL Routines

•Whichever type of customization you perform,you will be working with two mappings per target fact or dimension

‣An SDE (Source-Dependent Extract) mapto extract data from the source system

‣An SIL (Source-Independent Layer) mapto load data into the fact or dimension

•Category 1 mappings involve customizingexisting SDE and SIL mappings

•Category 2 customizations involve creatingnew SDE and SIL mappings from scratch




A Typical Informatica ETL Mapping

•Data extracted from sources using “Mapplets”, encapsulated business logic

•Data transformed using custom and pre-defined transformations

•Standard keys, tags added to data as it passes through ETL process

•Standard processes for adding surrogate keys, performing currency conversions etc

•

Mapping is then run and executed from the DAC Console and repository




DemonstrationPre-Seeded and Customized Informatica Mappings




Summary

•The Oracle Business Intelligence Applications are a packaged DW + Analytics solutionfor ERP and other data

•The base install of the Oracle BI Apps provides a pre-built set of data warehouse factsand dimensions, ETL routines, RPD metadata and control routines for a number of ERPmodules

•You can extend and customize these mappings to bring in data not covered by the pre-built routines

•More details can be found on our website or in our Oracle BI Apps Developer Course
