Managing Database Diagrams in Data View

You can open, save, copy, rename, and delete database diagrams from Data View. For each data connection, Data View displays any database diagrams that have been created for the database associated with the data connection. You can expand the Database Diagrams folder and see the tables included in each diagram.

Double-clicking a database diagram icon in Data View opens the diagram. Once you've opened a new or existing database diagram, you can drag tables and columns from Data View to add them to the diagram. You can then change the table's column properties, and define table relationships, indexes, and constraints.
