Creating a Query Model Class

You use this procedure to define a query or a composite model class in the Mobile Project. You can then model the new model class as a:

• Query

  Allows you to retrieve data based on specific selection criteria. In addition to this, you can define sort conditions to display the data in a specific order.

• Composite

  Allows you to select the attributes from more than one model class and maintain them collectively in a composite class. For example, a query output object that derives its result set from more than one model.

You can model the query and the composite in the same model class or in different model classes, as required.
