TopLink provides a mapping tool that links Java
objects to the database via JDBC such that the Java developer need not build SQL
calls and or face broken Java applications resulting from database schema changes.
Oracle Application Server offers additional solutions in the cache, portal, business
intelligence, and wireless areas:
Cache
Oracle Application Server Web Cache introduced a middle tier for the caching of
web pages or portions of pages. An earlier cache, Oracle Application Server Database
Cache, was used for caching PL/SQL procedures and anonymous PL/SQL
blocks but is no longer supported as of Oracle Application Server 10g.
Portal
Oracle Application Server Portal is also a part of the Oracle Developer Suite
(discussed later in this chapter) and is used for building easy-to-use enterprise
dashboards. The developed portal is deployed to the Application Server.
Business Intelligence
Application Server Business Intelligence components include the Portal as well
as Oracle??™s original business intelligence tools:
??? Oracle Reports, which provides a scalable middle tier for the reporting of
prebuilt query results
??? Oracle Discoverer, for ad hoc query and analysis
??? A deployment platform for JDeveloper custom-built OLAP and data mining
applications
These capabilities are discussed in Chapter 10.
