Chapter 6 Generating JDO Persistent Objects

Defining Java Classes

Steps To define JDO Java classes for your persistent business objects:

  1. Create a PowerAMC Object-Oriented Model Class Diagram targeted for Java.
  2. Define Java classes using any UML Class Diagram concept (generalization, association, interface, etc).
  3. Define the O/R mapping.

If the JDO product you will use does not support complex O/R mapping, you will need to define Java classes that can be easily mapped to relational tables.
