Overview

This example demonstrates the interactions of various Enterprise Object  Framework components to facilitate qualified fetches.  When a model file is dragged into the file well, a database connection is made and the attributes and relationships of the model are displayed.  By selecting fetch attributes and qualifying attributes, a dynamic query can be executed.
