About Oracle ADF Business Components Packages

Oracle ADF Business Components packages are very similar to Java packages: Just as Java packages organize classes into logical groups, Oracle ADF Business Components packages organize other business components (entity objects, associations, view objects, view links, and application modules) into logical groups. In fact, each Oracle ADF Business Components package corresponds to a Java package, which contains the Java classes for particular business components, if you have generated subclasses of the framework base classes.

However, Oracle ADF Business Components packages can also contain the XML files associated with the business components, and they specify metadata about the business components they contain.

We recommend putting business domain components (entity objects and associations) in a separate package from data model components (view objects, view links, and application modules). This allows you to reuse your business domain components with multiple sets of data model components.
