Research Of Emergency Vehicles Information Platform Based On SOA

Along with the development of computer science and technology, the research of methodology of software engineering also has an unprecedented progress on its way. From procedure-based software developing method to object-oriented software engineering, even to component-oriented software engineering, each improvement of software design method has played a key role to software evolution. After component-oriented, a new architecture model is coming to us which name is service-oriented architecture. Plenty of software paradigms using SOA are developed in a lot of professions, and they take a new software revolution here to us.In this paper, we research the developing method of emergency vehicles information platform based on SOA, the work is a try in the specific field using SOA to make an enterprise application. Emergency vehicles information platform is a system to supply a solution for the dealing of emergency business in the area of environment pollution incidents, the system which is developing for the environmental protection personals mainly has the functions of information retrieval, decision support and business assistance. The article depends on the superiority of SOA in the areas of architecture, supporting of business and others focuses on the method of reconstruction of emergency vehicles information system. Away from the traditional model's shortcomings, we discuss the new solution based on SOA. From the whole to local and from the abstract to concrete, our work makes a discussion on the aspects of architecture, modeling and building, and also give out the detail of how to build the emergency vehicles information platform based on SOA.First, in the level of architecture, we analyzed the emergency vehicles information platform, discussed the traditional architecture and its defects, then the new architecture of emergency vehicles information platform were proposed. In the two main aspects of business processing architecture and system architecture, we make the discussion of its composition.Second, in the level of service modeling, we give out the critical analysis of emergency data integration, the representation of emergency data and the integrate method of homogeneous data, heterogeneous data, unstructured data. The communication method in the new architecture is also studied. The encoding method and exchanging method were proposed.Then, we studied the services'using methods. The paper gives out the strategy of service discovery and service composition. In the specific field of emergency vehicles, we proposed the specific method of discovering and compositing of the emergency services.Finally, combined with aforementioned theoretical research and relied on the concrete project, we developed the software of emergency vehicles information platform. And the key issues in the developing procedure were discussed. At the last, the paper showed the prototype system of emergency vehicles information platform.
