Research of service-oriented analysis and design method

In order to solve the problem of rigidity in IT architecture and the existence of heterogeneous information islands within most enterprises, a novel service-oriented IT architecture-SOA (service-oriented architecture)emerges. The realization of SOA is embodied in the accomplishments of various IT applicable functions in the form of service encapsulation and the interconnection and interoperation of services in the form of loosely coupling. Service-oriented Analysis and Design (SOAD) is a specially designed mode of software modeling and developing based on SOA. This paper analyzes the structural model in a service-oriented application system. In accordance with the development code of RUP (Rational unified process), it demonstrates a SOAD mode and an example centered on architecture and activated with business process and use case.
