Middle-Tier Components of the SAS Intelligence Platform

Overview of Middle-Tier Components

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 environment includes the following third-party software and SAS software elements:

a Web application server
the Java Development Kit (JDK)
SAS Web applications, which can include SAS Web Report Studio, the SAS Information Delivery Portal, SAS BI Portlets, the SAS BI Dashboard, the 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
