Use the Control Center to display objects so that you can work with
them. Objects are displayed in the object tree
and the contents pane.
To display objects in the object tree and contents pane:
At the lowest level of the tree, folders of objects (such as tables) that do not contain other objects are displayed.
Systems, subsystems, instances, and databases are displayed in both the object tree and the contents pane. Objects that do not contain other objects are displayed only in the contents pane. For example, when you click a Tables folder, all of the tables in the database are displayed in the contents pane.
