• Many analysts don‟t have an IT background

• No time to learn expert coding

• Conduct data manipulation, analysis, and distribute reports

• Struggle to complete tasks without extensive knowledge of coding


Liberate Analysts (continued)

• No IT staff dedicated to SAS support

• Busy IT staff, managing a heavy workload

• Analysts create own SAS processes.

• Analysts wait for simple queries, reports, and small modifications.

• Analysts can complete many tasks on their own with EG.


Accessing Data for Analysts

• Access a variety of data sources, including SAS, Excel, and databases.

• Access virtually any data source, across platforms, with the appropriate

privileges and SAS products

• Can be done through a GUI

• As data is imported, it can be modified: dropping fields, changing variable

attributes, which worksheet or cells to import, and more.

• All without any coding!


14

Changing Column Properties

• Name: name of the variable. SAS naming restrictions apply.

• Label: text that is sometimes displayed in place of the variable‟s name.

The task has been saved but not run, so only the data and task appear in the

Process Flow. No output has been generated.


25

Running Tasks

Running a task:

• Saves all task roles and options associated with the task.

• Executes the task according to the options you have specified.

• Generates results.

• Closes the Task Window.

• Creates objects in the Process Flow and Project Tree for the task and

results.

The task has been run, so output now appears.


26

previous runs?” click Yes or No.


My Favorite Task – The Query Builder!

Query Builder is a graphical way analysts can:

29

• Join tables

• Select variables

• Filter data

• Sort data

• Change data source

• Compute columns

• Set up prompts

• De-dup observations

• Change query options

• Add titles, footnotes

• Limit output

• And more


Query Building for Analysts

• Intuitive, easy to understand and use, eliminates coding errors

• Queries become easy for non-programmers.

• Simple tasks don‟t require the support of a SAS programmer.

• Query Builder builds code that can be reused and modified.


31

Adding Columns to a Query

• Double-click or drag columns on the Tables list to add them to the query.

• The and buttons move columns up and down on the Select

Data tab.

• The button deletes columns.

tab.

• It can be manipulated in the same ways as other columns in the query.


35

Replacing a Range of Values


36

Adding a New Computed Column

50

The Table Analysis Task: PROC FREQ

The Table Analysis Task creates two- and three-way Frequency Tables.


Reporting for Analysts

• Analysts may depend on others to create simple reports.

• For simple changes, they need further assistance.

• Analysts leverage SAS reporting capabilities in an easy GUI, creating

custom reports and templates

PROC PRINT


52

Summary Reports: PROC Tabulate

• Once variables are assigned to task roles, you can begin arranging the

elements of the table in the Preview Area.

• One or two dimensions, concatenation and crossing, analysis and

classification variables, and statistics!


53

New Programmer Features in Enterprise Guide 4.3

Integrated Syntax Help

Using mouse-over or clicking F1 over a SAS keyword will display syntax

for the keyword, as well as a description


New Programmer Features in Enterprise Guide 4.3

Syntax Suggestion

When typing a SAS keyword, SAS will display a list of potential keywords

to use in code.

More Exciting New Features

Displaying libraries and data members, parentheses matching, program

formatting, and more!

These new features will change the programming experience of

every programmer, from novice to expert.


Missing Functionality

Some functionality is not available or is limited in EG:

• DDE

• X STATEMENT AND SYSTASK (need special permission from

administrator)

• SAS/AF Applications

• %WINDOW

• Statements, PROMPT options on LIBNAME statements, and interactive

environments such as the Report window

• DATA step debugger

• SAS statements that require user interaction and that do not work well in

a SAS batch program

• THE ENDSAS STATEMENT

Lots of documentation and ideas about how to address these items


Internal Resistance

• Experienced users have processes that work. If it‟s not broke, why fix it?

• Analysts may fear it is technical and they will not be able to use it.


Solution to Resistance – Hands-On Time!

• Programmers

Use current processes and streamline future development.

• Analysts

Achieve results with ease

Everyone will fall in love


Logistics of Implementation

• Part of Base SAS

• PC product

• Many have EG and aren‟t aware

• May need IT for installation or environment support

• Additional products may be needed to access data and other platforms.


Conclusion

• Something for everyone

• Streamline and standardize processes

• Increase efficiency and capabilities.

• Some resistance at first

• Once users get some hands-on time, they will never go back.

Enterprise Guide is truly an enterprise wide software for the future!
