Introduction to How SAS/ACCESS Works
This section explains the calls that SAS makes to the DBMS when you use
SAS/ACCESS features.
Note: Not all features are supported by all SAS/ACCESS interfaces. See the
documentation for your SAS/ACCESS interface to determine which features are
supported in your environment.
Before you use any SAS/ACCESS features, you must install base SAS, the
SAS/ACCESS interface for the DBMS that you are accessing, and any required DBMS
client software. See the SAS installation instructions and DBMS client installation
instructions for more information.
Each SAS/ACCESS interface consists of one or more data access engines that
translate read and write requests from SAS into appropriate calls for a speciļ¬c DBMS.
The following image depicts the relationship between a SAS/ACCESS interface and a
relational DBMS.
