This image describes the Oracle9iAS Discoverer architecture. There are four pathways through which you can access the underlying database:
- Administration applications access the database directly.
- Discoverer Desktop accesses the database directly from the client machine.
- Discoverer Plus uses a Java applet to access Discoverer Services, which connects to the database.
- Discoverer Viewer runs in a browser, and uses a servlet to access Discoverer Services, which connects to the database.
