You can use SAS data
sets (tables), the default SAS storage format, to store data of any
granularity.
A SAS table is a file
that SAS software creates and processes. Each SAS table is a member
of a SAS library. A SAS library is a collection of one or more SAS
files that are recognized by SAS software and that are referenced
and stored as a unit.
Each SAS table contains
the following:
-
data values that are organized
as a table of observations (rows) and variables (columns) that can
be processed by SAS software
-
descriptor information such as
data types, column lengths, and the SAS engine that was used to create
the data
For shared access to SAS tables, you can use
SAS/SHARE
software, which provides concurrent Update access to SAS files for
multiple users.
