When you complete the steps for creating a database connection, the Application Navigator should look similar to this when you expand the Application Resources panel. The database connection is now included as a resource for your application under the Connections | Database nodes.
To expand the connection and see the schema and database objects, click the + icons.
After adding the database connection to the application resources, you can optionally contract the Application Resources panel to increase the size of the Projects panel in the Application Navigator.
If you had selected the IDE Connections option while creating the connection, it would have been created in the Resource Palette, Connections panel, under the Database node, instead of in the Application Navigator.
The Resource Palette is used to manage catalogs and repository connections. Users working in a collaborative environment can share resources using catalogs. Users working alone can access the resources or groups of resources in a catalog where they are available in one place, for use with all applications.
