Working with the relationships graph
Use the relationships graph to create, change, and view the relationships in your database file.
By default, the relationships graph displays all of the tables in your current database file. You can add tables from other files (including external ODBC data sources), add more than one occurrence of the same table to the graph, or remove tables from the graph using the buttons described below.
You can use the undo and redo keyboard shortcuts to incrementally remove or replace changes in the relationships graph. To undo changes, press Ctrl+Z (Windows) or Command-Z (OS X). To redo changes, press Ctrl+Shift+Z (Windows) or Command-Shift-Z (OS X).
To access the relationships graph:
With the database open, choose File menu > Manage > Database.
The relationships graph appears.
