Note
When you open a diagram after the database has changed, the diagram reflects changes to the displayed database objects. New objects aren’t added automatically, and deleted objects are removed from the diagram.
A diagram stores layout and object references, but it doesn’t store full database object definitions locally. Therefore, restoring a diagram depends on the availability of the database and the objects referenced by the diagram.
When you reopen a manually saved diagram, dbForge Studio for SQL Server tries to connect to the SQL Server database that contains the diagram objects.
