Interface vs. Integrate SAS EG Camps

Run SAS Programs as separate files from one SAS EG project file.

Trouble-shoot data issues with query management. Do not depend on SAS EG for production runs.

Embed SAS Programs within SAS EG. Use SAS EG tasks to help

process data for analysis. Allow

managers access to data and reports.

What If SAS EG Could?

• Help with querying and validating? Query exploration and management

• Help with documentation? More portable package format (Notes, SAS Program, List, Log and Output file)

• Enforce standards and automation?

Fully compatible with SAS macros and menus•  Help with prototyping table layouts and performing

complex statistical analysis? Yes with feature to create custom tasks

Enterprise Guide Task Rules

Over 90 tasks to choose from

Each task is associated with a SAS Procedure- Simple Listing only for PROC REPORT Task may not contain all SAS Procedure options- Can copy and customize SAS code

Once you learn one task, other tasks are similar- Organized as tabs to specify variables and options

First access data set or query before selecting tasks

- Task needs to know the variables to display

Assure all variables exist in single data set or query

21

Which are the most profitable products?

Point-and-click the Sales data set to become active Point-and-click the Summary Tables Task Make the following tab selections

COLUMNS Assign SALES and QUANTITY as Analysis variables Assign CATEGORY and PRODUCT as Classification variables

TABLE Assign the following column variables: QUANTITY and SALES Assign the following row variables: CATEGORY and PRODUCT

RESULTS No need to save results to a data set

TITLES Enter text ‘Table 1.1 Sales Statistics by Product’

TAB Description*

* Instructions Required

22

SAS Enterprise Guide: Tasks

I. Project Setup Tasks II. Data Management Tasks

III. Analysis and Reporting Tasks

Process Training Required.

Logical sequence of events.

Organized approach to non-programming.

23

I. Project Setup Tasks

Project Setup Tasks Description_________Create Code Assign Libname statement ex. libname dfile ‘c:\data’;

Create Code* Create data set

ex. data test; etc.; run;

Create Format Create & Assign formats

ex. proc format; etc.; run;

* Programmer’s task - ex. proc reportKey Point: Access data sets and assign formats

24

II. Data Management Tasks

Data Management Tasks Description_________Create Query Add variables and formats

ex. salegrp, salegrp.

Apply subset condition

ex. 2002 sales data

Create Parameter Query* Add filter

ex. Select a product

* Can easily create a basic user-friendly interface Key Point: Subset data set, create new variables,

useful for ad-hoc requests

Proc SQL

25

Create Query Task:Merge Data Sets

Points to data set (does not copy the data set) Be careful NOT to move the source data sets Can create new permanent data set Single data set or query is required for tasks

BA

C

26

II. Data Management Tasks: Parameter Query

Example of one user prompt to ‘Select a Product’.

Can add more variables to restrict query.

Returns data set with only products selected.

Can use data set as source for EG tasks.

27

III. Analysis and Reporting Tasks

Analysis & Reporting Tasks Description__________Summary Table Sales Statistics Table, ex. proc

tabulate

Listing Detail Sales Listing, ex. proc print

Statistical Analysis Differences in yearly sales?

ex. proc t-test

Graphs How much have sales risen this year?

ex. proc gchart

Key Points: Select the appropriate task,

Query explore any intermediate dataset, Save all queries in project file

28

SAS Programming Options

Four Points of Custom Program Entry ________1. Execute code when first opening project file such as

setup.sas.

2. Execute code before or after running a task.

3. Insert custom code at predetermined points within a task to run with task. Examples include before or after DATA step or SAS Procedures and SAS Procedure statements or options.

4. Execute copied and customized generated code from task from a new program window.

Query Exploration and Management

LAB1

• Query 301 and labtest = ‘CHEM_ALB’• Query 302 and labtest = ‘HEM_ANC’

LAB2

• Query 301 and labtest = ‘CHEM_ALB’ • Query 302 and labtest = ‘HEM_ANC’

LAB

• Characterize Data• Save as permanent dataset

Intermediate Datasets

[Select Variables, Subset Condition, and Sort Order]

Recreate QueriesHow do you think dates are selected?

(DATA step update to LAB2)

(DATA step update to LAB)

Typical Business Model

Different Viewpoints of the Same Data

Viewpoint Example Question________________ Customer Which are the most profitable

customers?

Product What are the product sales acrossmarket segments –

Retail/Catalog?

Organization How successful are the marketingand sales campaign

promotions?

Once a table is created, it is easy to change the table to a different viewpoint!

32

Selecting Analysis and Reporting Tasks

How well do you know your business?

You’ve got questions, Enterprise Guide has answers!

PRODUCT? - ShoesCUSTOMER? - AcmeREGION? - NorthernMARKET SEGMENT? - Retail SalesTIME PERIOD? - 4th Quarter, 2001PRODUCT GROWTH? - Slippers

WHICH IS THE BEST ?

SAS Enterprise Guide Best Practices Tips:

1. Some level of training is required.

2. Write to SAS programs instead of embedding the SAS programs to keep as separate files.

3. Take advantage of Notes Task to document steps.

4. Apply ‘Save As’ instead of ‘Save’ to prevent accidental replacement of another project file.

5. Be careful when saving files when multiple projects opened.

SAS Enterprise Guide Best Practices Tips:

6. Take advantage of process flow diagram to visualize project code and tasks.

7. Take advantage of split panel to simultaneously view dataset and SAS program.

8. Take advantage of order list option to create batch jobs.

9. Take advantage of viewing each HTML/RTF/PDF file, for example, when creating multiple files.

10. For best debugging, keep all unique intermediate dataset names to view each data step sequence.

34

SAS Programmers Tool - Syntax

proc report data=mydatea.sales nowd split="*" headline; column product year,(quantity sales pct_prd) quantity=grd_tot sales=grd_pct; define product / group 'PRODUCT'; define year / across 'Sales by Year' center; define quantity / sum 'N' center format=comma6.; define sales / sum 'Total' format=dollar8.; define pct_prd / computed '% Total' width=5 format=pctf.; define grd_tot / sum 'QNTY Total' format=comma6.; define grd_pct / sum 'SALES Total' width=5 format=dollar8.; compute before; gt1=_c3_; gt2 = _c6_; gt3 = _c8_; endcomp; compute pct_prd; _c4_ = (_c3_/gt1)*100; _c7_ = (_c6_/gt2)*100; endcomp; rbreak after / summarize skip ol ul; compute after; product = 'Total'; endcomp;run;

Yes, you can write your own code.

41

Moving EG Code to Production All Enterprise Guide code can be exported

Enhance EG code with style options

Very useful to develop prototype without writing code

For any task, select Preview Task Code

Create Code Task (Programmer’s Task)
