Group Decision Support Platform Based On Soa Service Modeling Research

Group decision support system is a composite system of computer technology, communication technology and decision support. Group decision support system can help to execute semi structured group decision. The development of Internet made distributed group decision a new trend. Service-Oriented Architecture is a kind of IT architecture style. By building business logic and technology abstract service, SOA can separate business logic and its realization technology, which can reduce the heterogeneous, meet the need of interoperability and fast moving business, and support distributed group decision.At present, service modeling method for group decision support platform is still inadequate. In this paper, we studied the current available service-oriented modeling methods, analyze its inadequate and proposed a service modeling method that is suitable to group decision support platform. Current model-driven service modeling method lacks of intermediate level, thus source model has low heterogeneous with target model, because source model lacks of detail information. This paper improved the existed model and proposed a Business-Oriented and Model Driven Agile Service Modeling method. The method is business-centric and uses model-driven architecture. This paper introduced a technique to convert UML to a WSDL document as the transformation example and then transform WSDL into realization code. By two stage transformation, this method can produce better quality code. Business-centric feature improve the opportunity to reuse, and SOA based architecture featured heterogeneous and interoperability.This paper proposed the process of Business-Oriented and Model Driven Agile Service Modeling method including domain decomposition, business process modeling, interface modeling, service design and model transformation. Domain decomposition, business process modeling and interface modeling composed of service-oriented analysis. Service design and model transformation composed of service-oriented design and realization. In the end, this paper modeled for the problem management system of a group decision support platform and proved that Business-Oriented and Model Driven Agile Service Modeling method is feasible.
