Creating Business Services for the Model Project

Business services provide a level of abstraction from the underlying data source. Business services govern the interaction between the rest of the application and the data source, providing validation, specific services, and other business logic.

To create business services :

1. Make sure you have created an application workspace with the technology stack you want to use:
   • If you want to use an Oracle framework to implement J2EE design patterns for your business services, we recommend using one of the default technologies scopes.
   • If you want to implement your own framework for business services, we recommend the non-default technology scope, or all technologies technology scope.
   • If you want to use web services to expose existing business services, we recommend using the all technologies scope.
2. In the Application Navigator, under your application workspace node, right-click the Model project and choose New to open the New Gallery.
3. In the Categories list, expand Business Tier.

   Under the Business Tier node, you will see categories pertaining to your chosen technology scope. For information on proceeding, see one of the following topics:
