An advantage of the
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
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, refer to 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.
