An advantage of the
SAS/ACCESS interface to
CA-Datacom/DB
is that it enables SAS to read and write
CA-Datacom/DB data directly using SAS programs. This section presents
examples using
CA-Datacom/DB data that is described by
view descriptors in SAS programs. For information about the views and sample data, see
Data and Descriptors for the Examples. Throughout the examples,
the SAS terms
column and
row are
used instead of comparable
CA-Datacom/DB terms, because this section illustrates using SAS
procedures and the DATA step. The examples include printing and charting
data, using the SQL procedure to combine data from various sources,
and updating SAS 6 and SAS 8 and later versions of SAS data sets with
data from
CA-Datacom/DB.
For more information about the SAS language and procedures used in
the examples, see the documents listed at the end of each section.
At the end of this section,
Performance Considerations presents some techniques for using view descriptors efficiently in SAS programs.
