What Is a SAS Stored Process? A SAS Stored Process is a SAS program that is hosted on a server and described by metadata can be executed by many of the new clients in the SAS ® 9 Intelligence Platform SAS Stored Process

Where Is a Stored Process Defined and Stored? A stored process is a SAS program defined by metadata and stored in a source code repository. Most of the capabilities of SAS programs are still available to you. proc report data=sashelp.class nowd; column name age height; define name / order 'Name'; define age / display; define height / display; run; SAS Stored Process Source Code Repository Metadata Server Metadata Server.SAS file

What Can a Stored Process Access? Because a stored process is a SAS program, it can access any SAS data source or external file. SAS Stored Process SAS Data Sources External Files

What Can a Stored Process Create? Because a stored process is a SAS program, it can create new data sets, files, and report output in a variety of formats. SAS Stored Process SAS Data Sources External Files SAS ODS Output SAS Catalog Entry Results Package

Conclusion SAS Stored Processes will accept user input parameter values so that the code is not static. SAS Stored Process code is not embedded into client applications. SAS Stored Process programs can be invoked from multiple clients, such as Web browsers and desktop applications. Stored process programs also ensure security and application integrity because the code is contained on a server and can be centrally maintained and managed from the server. Extend the analytical power of SAS to non SAS programmers.
