Back and Forward |
Retrace your steps. Navigate between hyperlinked database objects and their dependent objects and components. Move between—
- An object and its dependencies, and vice-versa
- An index or trigger and the table to which it refers, and vice-versa
- A collector type and the base type of table it is related to
- A synonym and its base object
You can also use the Forward and Back buttons in conjunction with Up One Level. |

Up One Level |
Change hierarchy levels in the DB Navigator tree.

TIP: Use Back to return to the level where you first used moved up. | |

- When you select a specific object the details pane shows attributes of the selected object.
