The service architecture of Integrated Financial Enterprise

Service-oriented architecture provides effective techniques to solve the problems of the enterprise application integration and to implement the business process re-building. In this paper, a reference implementation program of the business, semantics and service three-layer Integrated Financial Enterprise service architecture (IFE) is proposed. This program classifies the knowledge object of the banks´ business domain through knowledge modeling, makes the description of the semantics, relationships, and levels of business concepts, defines the banks´ business process content and boundaries, constructs the standardization of business processes, and forms business use cases. It divides the business activities into the minimum business semantic units, and forms the service metadata models. The authors propose the application-layer communication protocol Financial Level 7(FL7) for IFE. FL7 gives a definition of compliance service by using the semantic description model of the business components, and also gives the technical communication protocol between systems and system components by analyzing and designing the syntax, element, session and message mechanisms of the system components. All of them conduce to the solutions to problems of the business process standardization and the implementation of the business and technical architecture.
