Designing Enterprise Objects

The Enterprise Objects Framework and the applications you build with it revolve around the enterprise objects that you design. Designing these objects, then, is in many ways the essence of creating an Enterprise Objects Framework application. This chapter explains the mechanics of designing enterprise objects, describes their structure and interaction with the Framework, and explains how you can take advantage of features provided by the Framework.

Designing an enterprise object entails three major steps:

• Designing your schema
• Modeling the enterprise object
• Implementing the enterprise object

This chapter uses selections from the Enterprise Objects Framework on-line examples to explain the principles of designing an enterprise object. In particular, the chapter focuses on the Customer entity in the Rentals database. A customer is a video store member who is authorized to rent videos.
