Implementation

Many BC4J-VSM associations (examples: order items to orders, order to user) are implemented in the oracle.otnsamples.vsm.entities package.

The Oracle9i JDeveloper environment comes with comprehensive tools support for putting the BC4J framework components to use in J2EE applications. You use interactive wizards, editors, property inspectors, and UML diagrammers to create, enhance, and deploy your BC4J components. These tools are tightly integrated within a complete Java IDE that includes debugging, deployment, and source control support, so you can work from the beginning to the end of your J2EE application development lifecycle with one tool.

Business component wizards can automatically create associations based on the database constraints already defined in the database. They can also create database constraints based on the associations you define.

You can define and edit associations in the Association Wizard and Editor. You can also generate default associations, based on foreign key constraints in existing tables (reverse generation), by using the Entity Object Wizard and Editor, Business Components Project Wizard, or Package Wizard. You can optionally add foreign-key constraints to tables based on the associations you've defined in the Association Wizard and Editor (forward generation). If you add database constraints after generating your business components, you can automatically create the corresponding associations in the following ways: Use the Synchronize tool to create associations based on new foreign key constraints. Click Finish in the Entity Object Editor to create the new associations (the attributes corresponding to the foreign and primary keys must be included in the entity objects).

You can define and edit view links in the View Link Wizard and Editor. You can also generate default view links, based on existing associations, by using the Entity Object Wizard and Editor, Business Components Project Wizard, or Package Wizard.
