The SAS Web Infrastructure Platform is a collection
of services and applications that provide common infrastructure and
integration features to be used by SAS Web applications. These services
and applications provide the following benefits:
-
consistency in installation, configuration,
and administration tasks for Web applications
-
greater consistency in users' interactions
with Web applications
-
integration among Web applications
as a result of the ability to share common resources
The following services and applications are included
in the SAS Web Infrastructure Platform:
can be used to enable
your custom applications to invoke and obtain metadata about SAS Stored
Processes. Web services enable distributed applications that are written
in different programming languages and that run on different operating
systems to communicate using standard Web-based protocols. The most
common protocol is the Simple Object Access Protocol (SOAP).
contains graph applet
JARs that are shared across SAS Web applications. They display graphs
in stored processes and in the SAS Stored Process Web application.
SAS Web Infrastructure Services
provide a common infrastructure
for SAS Web applications. The infrastructure supports activities such
as auditing, authentication, configuration, status and monitoring,
e-mail, theme management, alert registration and notification, collaboration,
and data sharing across SAS Web applications. The infrastructure also
includes Web service interfaces that enable Java and .NET desktop
applications to access the authentication service. SAS Enterprise
Miner and other analytic products and solutions use these services
for user authentication.
provides a common user
authentication mechanism for SAS Web applications. It displays a dialog
box for user ID and password entry, authenticates the user, and launches
the requested application. SAS Logon Manager supports a single sign-on
authentication model. When this model is enabled, it provides access
to a variety of computing resources (including servers and Web pages)
during the application session without repeatedly prompting the user
for credentials.
You can configure SAS
Logon Manager to display custom messages and to specify whether a
logon dialog box is displayed when users log off.
In addition, you can
use third-party products in conjunction with SAS Logon Manager to
enable users to access multiple Web applications within the same browser
session.
provides a common mechanism
for managing preferences for SAS Web applications. The feature enables
administrators to set default preferences for locale, theme, alert
notification, and time, date, and currency display. Within each Web
application, users can view the default settings and update their
individual preferences.
enables users to create
comments related to business intelligence objects. Users can then
reply to, search for, retire, delete, or add attachments to existing
comments. This feature enables the capture of human intelligence and
supports collaborative decision making related to business data.
SAS Stored Process Web Application
executes stored processes
on behalf of a Web client and return results to a Web browser. The
SAS Stored Process Web application is similar to the SAS/IntrNet Application
Broker, and has the same general syntax and debug options.
SAS Web Administration Console
provides features for
monitoring and administering middle-tier components. This browser-based
interface enables administrators to do the following:
-
view a list of users who are logged
on to SAS Web applications, send e-mail to active users, and manage
users’ logins during system maintenance by preventing, terminating,
and restarting user access
-
view audit reports of logon and
logoff activity
-
create, delete, and manage permissions
for folders on the SAS Content Server
-
view configuration information
for each middle-tier component
-
dynamically adjust logging levels
for some Web applications
stores digital content
(such as documents, reports, and images) that is created and used
by SAS Web applications. For more information, see
SAS Content Server .
enables the deployment
and execution of workflows and processes that are integrated with
certain SAS applications and solutions. The SAS Workflow Studio client
application enables business users to quickly create or modify process
maps to be executed by the engine.
By default, the SAS
Web Infrastructure Platform uses the SAS Framework Data Server to
store alerts, comments, workflows, and SAS Content Server data. During
installation, you can choose to store this data in a third-party database
instead.
