Request Broker service technology (also called software agent technology) is a hot method to deal with complex computing and software development to solve distributed application environment. In recent years, with the rapid development of Internet technology, the development of the WebService, XML, and other technologies, Request Broker service technology into a new stage, Request Broker technology from traditional computers, artificial intelligence, automatic control and applications quickly extended to e-commerce, e-government and other fields, to become the technology of choice for application integration. First, the analysis and research the technical characteristics Request Broker service technology, the development process and its applications, CORBA, COM / DCOM, EJB, WebService technology advantages and disadvantages are analyzed and compared. Meticulous research paper on the origin of the current state-of-the-art WebService technology, definitions and performance analysis of domestic and foreign common use of WebService technology for application integration mode, and pointed out that a single central integration node application integration mode in our country defects on the e-government application system. Secondly, for the shortcomings of the above model, this paper as the background to the Ministry of Public Security, provincial and municipal application system request generation services, WebService, XML markup language technology foundation for e-government to build a The multi-level application systems interoperable distributed applications the platform design ideas and frame structure; design a matching set of interoperable platform overall framework, described in XML markup language defined, common data request, data transfer agreement data routing, data the scheduling standard protocol, combined with practical work to develop the system. For the common platform requirements, to achieve a \Through the application of system interoperability platform, the integration and coordination of heterogeneous, distributed applications, different development languages, different operating systems, different database types, different database table structure system capable of organic work together, so that more than class distribution, isolated from each other, heterogeneous applications orderly integrated into a collaborative network to form an overall coordinated interaction \This paper describes the design ideas of the platform, the structure of the model, consisting of modules and standard protocols, the end of this article described three actual cases distributed application system interoperability platform application prospects.
