Overview of SAS Servers
The SAS Intelligence Platform provides access to SAS functionality through the
following specialized servers:
Note: In the SAS Intelligence Platform, the term “server” refers to a program or
programs that wait for and fulfill requests from client programs for data or services.
The term server does not necessarily refer to a specific computer, since a single
computer can host one or more servers of various types.
the SAS Metadata Server, which writes metadata objects to, and reads metadata
objects from, SAS Metadata Repositories. These metadata objects contain
information about all of the components of your system, such as users, groups, data
libraries, servers, and user-created products such as reports, cubes, and information
maps.
