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.


This figure is a screenshot of the panels used when working with a meta-schema.

Figure 1. Viewing the schema

Icons on the diagram and in the Database Structure view indicate when a column's status has been changed: added (), modified (), or removed ().

A red circle icon with a white exclamation point, found in the upper left corner of the visual representation of the table, identifies a table that has been modified. To view the specifics of the modification, hover over the icon with your mouse.
