| Architecture of the SAS Intelligence Platform |
Middle Tier
The middle tier of the SAS Intelligence Platform provides an environment in which the business intelligence Web applications, such as SAS Web Report Studio and the SAS Information Delivery Portal, can execute. These products run in a Web application server and communicate with the user by sending data to and receiving data from the user's Web browser. The middle tier applications rely on servers on the SAS server tier to perform SAS processing, including data query and analysis.
The middle tier includes the following third-party software and SAS software elements:
-
a Web application server
-
the Java Development Kit 5
-
SAS Web applications, which can include SAS Web Report Studio, the SAS Information Delivery Portal, SAS BI Portlets, the SAS BI Dashboard, SAS Help Viewer for the Web, and other SAS products and solutions
-
the SAS Web Infrastructure Platform, which includes the SAS Content Server and other infrastructure applications and services
-
SAS Shared Services
-
a Java remote method invocation (RMI) server, which enables access to SAS Foundation Services and associated extension services
