Viewing a meta-schema

Once a database meta-schema file has been created, it can be viewed and enriched with information that is not present in the database. Opening a meta-schema file displays it as a diagram for viewing and editing.

Each table is described by a table in the diagram. The structure of the database tables is displayed in the Database Structure view.
