Oracle: A
link is a database object that you use to identify an object stored
in a remote database. It contains stored path information. It might
also contain user name and password information for connecting to
the remote database. If you specify a link, SAS uses it to access
remote objects. If you omit this option, SAS accesses objects in only
the local database.
Sybase: This
option lets you link to another database within the same server to
which you are connected. If you omit this option, SAS can access objects
in only your default database.
