Design

JDeveloper and BC4J provide tools for building applications that model interactions in the real-world. To build the Virtual Shopping Mall, OTN developers took full advantage of these capabilities by identifying entities and relationships in a physical shopping mall. By taking this approach, they could use JDeveloper wizards to generate:

• XML code to describe the entities and link them to the database
• Java code to define their behavior

JDeveloper and BC4J take care of the framework and plumbing code, leaving the developers free to focus on business logic.

Other aspects of the BC4J-VSM design are covered in various lessons in this tutorial series.
