Within the Administration perspective, the Navigator view contains the database object tree display. It is similar to the Data Source Explorer view in other perspectives. The Navigator displays objects in the Object List Viewer, allowing you to view, create, and modify objects, as well as perform other administrative tasks.
The object categories vary depending on the type of connection. Right-click an option in the tree to list its objects in the Object List Viewer. The double-click action is indicated by a check.
