Unit 5 Completed

Service Coupling

1.) Using research and your own experience, explain why the service contract is a permissible focal point for coupling in a service. What characteristics of the service contract will allow the service to evolve even when loosely coupled to logic and to customers?

2.) What are the short term and long term consequences of designing a system with contract-to-logic coupling? What are the effects on the service itself and what are the effects on the overall service inventory when this occurs? Using research and your own experience, identify at least two situations that could facilitate contract-to-logic coupling in practice.

3.) Explain the type of coupling (and hence dependencies) that can be expected for task services, utility services, and entity services. How does coupling at the service level affect the capabilities of the service that is dependent on either external or internal implementations?

4.) Describe an overall strategy for the best way to incorporate vendor specific platforms and solutions into a service-based solution. In your analysis, include considerations of the type of service that should have the coupling and how this service can best abstract the dependency from any other services to which it is connected.
