Research on service identification methods based on SOA

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. Based on SOA, Service-oriented Analysis and Design (SOAD) is a specially designed method of software modeling, analyzing and designing. In the whole process of which, service identification is the most significant. This paper analyzes the structural model in a service-oriented architecture, in combination with the development code of RUP (Rational unified process), it demonstrates three most widely used methods service identification in an SOAD procedure and provides with an example.
