3.1.1. Using CDM RuleFrame • Save the project Now you can use oracle.jheadstart.model.adfbc.v2.JhsApplicationModuleImpl as the super class of your custom Application Module framework extension. Suggestion: In the Base Classes wizard page, use the Browse button to find the desired base class. In the Search field, type in the first letters of the class name, and the dialog will show all available classes that satisfy the base class requirements. CDM RuleFrame is a PL/SQL based framework for implementing business rules in the database, tightly integrated with Oracle Designer. Headstart Oracle Designer. Add on to Oracle Designer that includes CDM RuleFrame: http://www.oracle.com/technology/products/headstart/index.html If you use CDM RuleFrame to implement business rules, you want the errors reported by CDM RuleFrame to be displayed nicely in your generated web application. Using JHeadstart this is easily accomplished by using a special application module super class shipped with JHeadstart: RuleFrameApplicationModuleImpl. So, when using CDM RuleFrame, your application module base class should extend RuleFrameApplicationModuleImpl rather than JhsApplicationModuleImpl. Note that RuleFrameApplicationModuleImpl extends JhsApplicationModuleImpl in turn; so all standard JHeadstart functionality is still available. 3 - 4 Creating Business Components JHeadstart Developer's Guide
3.2. Creating the Entity Object Layer 3.2.1. Review Database Design This section discusses the development tasks related to creating the entity object layer. The following topics are discussed: • Review Database Design • Creating First-Cut Entity Objects and Associations • Renaming Entity Objects and Associations • Generating Primary Key Values • Setting Entity Object Attribute Properties used by JHeadstart • Implementing Business Rules A sound database design is critical to successfully building a performant ADF Business Components layer. Providing guidelines for sound relational database design is outside the scope of this developer’s guide, however, some guidelines directly impacting the behavior of your web application are discussed below: • If you are in the position to create or modify the database design, make sure all tables have a non-updateable primary key, preferably consisting of only one column. If you have updateable and/or composite primary keys, introduce a surrogate primary key by adding an ID column that is automatically populated. See section 3.2.4 Generating Primary Key Values for more info. Although ADF Business Components can handle composite and updateable primary keys, this will cause problems in ADF Faces pages. For example, an ADF Faces table manages its rows using the key of the underlying row. If this key changes, unexpected behavior can occur in your ADF Faces page. In addition, if you want to provide a drop down list on a lookup tables to populate a foreign key, the foreign key can only consists of one column, which in turn means the referenced table must have a single primary key column. • Ensure that all the primary key, unique key, and foreign key constraints and check constraints that logically exist, are explicitly defined as database constraints in your database server. When you create ADF Business Components, these database constraints are stored in the Entity Object XML file. JHeadstart uses this constraint information to generate user-friendly error messages when a database constraint is violated. 3.2.2. Creating First-Cut Entity Objects and Associations Use the JDeveloper wizard Business Components from Tables to create entity objects for your database tables. You can find this wizard in the New Gallery. On the “Create Entity Objects” wizard page, press the Query button to see all tables you created in the previous exercise. Make sure you specify a proper package name for the entity objects, based on the naming conventions that you specified for your project. See chapter 2 for more info on naming conventions. Do not yet create default updateable or read-only view objects and do not create an application module using the wizard for two reasons: JHeadstart Developer's Guide Creating ADF Business Components 3 - 5
