Extracting Your Schema

JADE enables you to extract multiple schemas, a complete schema, or parts of a schema; for example, as a backup before you reorganize your database, install a new release of JADE, or if you want to pass code to another JADE developer.

If you extract a class that has an inverse to a property of another class that is not part of the same extract operation, it is your responsibility to ensure that you extract the other class as well or that the other class already exists in the target schema with the appropriate property.

You can resize the Extract dialog (by clicking on the form border and then using the mouse to drag the form to the required position when the cursor changes shape to a double-ended arrow); for example, to enable you to display a greater number of classes, interfaces, and methods when performing a selective extract.

To extract a user-defined schema

  1. In the Schema Browser, select the schema that you want to extract, if it is not the current schema.

  2. Access the Extract dialog by performing one of the following actions.

    • Select the Schema Extract command from the File menu.

    • Select the Extract command from the Schema menu.

    • Click the Extract toolbar button.

    • Press Ctrl+Alt+E.

The Extract dialog, shown in the following image, is then displayed.
