Rule based business service identification using UML analysis

Practitioners and vendors are now building application systems with business level services to better leverage business goals with SOA. However, due to the subjective nature of business activities specification and their complex relations, there still lack a sound normative business service identification approach. In this paper, we present a UML based analyzing process for business service identification. We first analyze relations between business logic and application implementation, and build a business service model to denote the factors in business service identification. We use UML as an analysis tool. By clustering UML use cases in alignment with business rules, we obtain business level services that fully demonstrate traits described in the proposed service model. Thus business services fully comply with SOA principles are identified with lower level functional components. A mortgage loan process is analyzed as a case study, and the result shows this approach is promising in analyzing business level services.
