In the past, SAS has been used to read data from other Windows data sources,
e.g., Microsoft Access tables using SAS/ACCESS for ODBC, and to control other
external Windows applications using Dynamic Data Exchange (DDE). SAS is, of course,
available as a Windows application itself and can now be used as an external application
for those other Windows applications. This role reversal expands the range of uses for
SAS in the Windows environment in areas where SAS has not been traditionally the firstchoice
application. The ability of SAS to read and maintain data from a wide range of
sources can now be used throughout the Windows arena.
Further discussion on SAS Enterprise Guide, a thin-client application for the Windows
client platform that uses SAS Integration Technologies to communicate with SAS
installations on remote servers, can be found in Chapter 6 “Developing SAS Applications
Using SAS Enterprise Guide.”
