Main Description

In this stage, service contracts and related processing logic (including orchestration and business rules) are designed. The services are designed from the logical models created during service-oriented analysis.

The services are assembled into compositions, while maintaining the loose coupling inherent in “contract-first” design. During design, the assignment of services to layers is also refined.
