such assumptions.

transformers (i.e. processes).

4. The service operational model showing the different interactions and dataflow

diagrams as well as the involved processes models.

5. Realization of the service charge model. (i.e. show how to generate bills for

services using the shopping cart service)

6. The data architecture.

7. The exchanged Message formats.

8. The interfaces of the subsystems.
