Relating modules

In the main screen of Data Crow you'll find a menu called "modules". This menu contains wizards to customize, create and relate modules. In this chapter is explained how you can relate two modules. Using this wizard you can make a parent child relation between two modules. The relationship between Audio CDs and Audio Tracks is a good example of such a relationship. In the example the Audio CD module is the parent module of the Audio Track module (audio tracks could never exist if it wasn't for the audio cd).

Starting the wizard

Start the wizard by selecting "Relate Module Wizard" from the modules menu.

Selecting the parent module

In the first step you select the parent module.

Selecting the child module

In the last step you select the child module.

Finishing the Wizard

After all information has been supplied press the "finish" button or the "finish & new" button. The "finish" button finishes the process. Data Crow needs to restart before the changes can become apparent. The "finish & new" button finishes the process and restarts the wizard (which can be useful when you want to create more relationships).
