• SAS data sets, which are analogous to relational database tables.
• SAS SPD Engine tables, which can be read or written by multiple threads.
• SAS SPD Server, which is available as a separate product.
• SAS OLAP cubes.
• The SAS Web Infrastructure Platform Data Server, which is the default location for
middle-tier data such as alerts, comments, and workflows, as well as data for the
SAS Content Server. The server is provided as an alternative to using a third-party
DBMS. (The server cannot be used as a general-purpose data store.)
In addition, SAS provides products that enable you to access data in your existing third-
party data stores and ERP systems, including:
• the SAS/ACCESS interfaces, which provide direct access to a variety of data stores.
For a complete list, go to http://support.sas.com/software/products/access/.
• SAS Data Surveyor for SAP, which enables you to build SAS Data Integration
Studio jobs that read data directly from SAP R/3 and SAP Business Warehouse

Platform,” on page 17.
SAS Server Tier
SAS Server Tier Overview
The SAS server tier includes the SAS Metadata Server and several compute servers that
execute SAS analytical and reporting processes for distributed clients. These servers are
typically accessed either by desktop clients or by web applications that are running in the
Note: In the SAS Intelligence Platform, the term server refers to a process or processes
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.
SAS Metadata Server
The SAS Metadata Server controls access to a central repository of metadata that is
shared by all of the SAS applications in the deployment. The SAS Metadata Server
enables centralized control so that all users access consistent and accurate data. The
metadata repository stores information about the following:
• the enterprise data sources and data structures that are accessed by SAS intelligence
• the content that is created and used by SAS applications. This content includes
information maps, OLAP cubes, report definitions, stored process definitions, and
portal content definitions.
• the SAS and third-party servers that participate in the system.
