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:
-
-
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, 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
-
a Java remote method invocation
(RMI) server, which enables access to SAS Foundation Services and
associated extension services
