Creating a Package of Data Model Components

Oracle ADF Business Components packages organize other business components into logical groups. For more information, see About Oracle ADF Business Components Packages.

We recommend using packages to separate your data model components (view objects, view links, and application modules) from your business domain components (entity objects, associations, and domains). This allows you to reuse your business domain components with multiple sets of data model components. For more information, see the related topics list.

You can create a package of data model components in any of the following ways:

When you create a package of business domain components using the Create Entity Objects From Tables dialog, select I nvoke dialog to create default Data Model Components to open the Default Data Model Components Wizard.
In the System or Application Navigator, right-click a package of business domain components and select New Def ault Data Model Components to open the Default Data Model Components Wizard.

Using the Default Data Model Components Wizard will create:

Simple view object definitions, with a single entity object usage and a query of SELECT * FROM <TABLE>, where <TABLE> is the table on which the entity object is based
Simple view link definitions, linking the view object definitions based on associations between their entity usages
An application module with a data model containing instances of all the view objects related in all the possible ways specified by the view links.

You should edit these business components later. For more information, see the related topics list.
