Using the Data Dictionary List Panel
The list panel displays a list of tables and their columns. The list panel can list the table names by either their logical names or their physical names. Click the appropriate button on the toolbar to switch between the two views. The list is displayed in alphabetical order, so the order may not be the same in both views. Both views function in a similar manner.
In the list panel, you can navigate using the following options:
Click the right arrow icon to expand a table to show its columns.
Click the down arrow icon to collapse the column list for a table. Optionally, collapse all column lists by using the Collapse button.
Click the column name to display information about the column in the detail panel.
If the detail panel is in related table view, click the table name to view its related tables. If the detail panel is in table detail view, click the table name to display its information.
