Working with Process Component Architecture Models 

Use

In a service-oriented architecture of business applications, you ideally initially model your application prior to implementation. This means that you can answer fundamental questions such as what components the application comprises of, which services the individual components offer, and how the various different components interact with each other before you begin implementation. A governance process ensures that by using models, all services are always identified and defined in the same way to avoid redundancies.

The models are not system-landscape-specific. Later on, they provide useful information when implementing services, as well as during any configuration that may be required. Furthermore, the models document different aspects of a business process, increase understanding of applications across departments and businesses thereby reducing costs when applications need to be changed or enhanced in a later release.

Prerequisites

See the prerequisites in the Enterprise Services Repository section.

Procedure

...

       1.      Familiarize yourself with the methodology of various models.

More information: Defining Process Component Architecture Models

       2.      On the basis of the modeling principles, create your own models using the modeling environment.

       3.      Use your models to determine which design objects you require for your application (interfaces, data types, and so on) and then define them in the ES Repository.
