The service architecture of commercial bank

Service-oriented architecture provides effective techniques to build new commercial bank. An implementation program of the business, the semantics and a three-layer service-oriented architecture are proposed in this paper. The knowledge object of the banks´ business domain is classified through knowledge modeling; the semantic description, the relationships and levels of business concepts are given; the banks´ business process content and boundaries are defined. The program in the paper divides the business activities into the minimum business semantic units, and forms the service metadata models. The application-layer communication protocol Financial Level 7 is represented, which gives a definition of compliance service by using the semantic model of the business components, and also gives the technical communication protocol between systems and system components by designing the syntax, element, session and message mechanisms of the system components.
