Modeling Application Services 

Use

You model application services so that you can store the business process logic of your project model. In mapping your model, you can use other entity and external services as well as their corresponding operations, input and output parameters to connect to the CAF environment with the outside world.

With application service, you can also automatically provide enhanced infrastructure services like authorization, tracing, and transactional handling based on metadata information from the CAF service layer.
