| Long-term since, due to the various government departments fragmentation, computer application system start is not a lack of unified planning, effective and macro guidance and other factors, resulting in the current e-government application system independent, data standard is not unified, data cannot be shared, information isolated island phenomenon. For example, in a government applications use multiple departments, each built an application must build a set of basic data platform, to realize the interaction and sharing among the various departments of the data, so that multiple applications will be more basic data platform, easily lead to data inconsistency, data not fully share and utilize. The use of such that the comprehensive application of it down.The current data service platform in e-government problems, this paper put forward the "unified data service platform" concept, from the point of view of data services system of premises, the actual demand a full investigation bureau of premises unified data services, designed to meet the local department of real estate exchange and sharing information resources, to achieve the goal, I has completed the following research work:1, the real estate agency industry development status and background, with the rapid development of modern technology, puts forward the key technology to develop the system, including WebService, XML, EJB, a solid foundation for the design of system.2, after the detailed demand investigation, according to the particularity of business premises Bureau, the study is based on the functional requirements for uniform data service system of real estate agency and the non functional requirements.3, the system architecture design, functional design, database design, interface design etc.4, the key function of the system in detail, including the platform service customization, the service configuration, high speed web services and other functions, and a great deal of experimental data in high speed web services.5, analysis of the system and the test performance and function, the subject is mainly reflected in the interface part, data interface can be divided into property dataquery, data query, ownership of graphics data query, the main test interface for accessing large machine database load, test result data service supports up to 20 application of a single application server visit at the same time, the maximum number of concurrent users for 200, fully meet the system requirements. |
