Modeling and Refining the Service-Oriented Requirement
Xiaoxia Cao, Huaikou Miao, Qingguo Xu · 2008
Service-oriented architecture (SOA) and model-driven architecture (MDA) are the hottest topics of discussion currently with regard to enterprise architecture. This paper presents an approach for transforming computer independent model (CIM) to platform independent model (PIM) separating implementation technologies and platforms from the business logic in an easy and uniform way. The approach mainly includes the following two parts. The first part gives a service-oriented way to model the requirement. The requirement model addresses software as a service model for forward looking enterprise; the second part gives a model refinement mechanism and a set of refinement rules. The refinement mechanism and rules can transform the requirement model to a set of loosely coupled services and can match these services to their suitable components and interfaces. In a word, this paper provides a uniform way to transform business requirements to their service implementation, and this transforming process can be clearly traced and analyzed.
