Study On Heterogeneous Information System Integration Of Market Of Person With Ability Based On Web Services

Nowadays, multiform markets of person with ability are playing a very important role in disposition of human resource. But, with its service functions becoming more and more diversified, some defects such as the difficulty of integration and intercommunion among different systems as well as subsystems in a single system increasingly emerged. This paper just aims at this problem and carries out the interrelated research work which includes the solution of integration among heterogeneous information systems of the market as well as subsystems in a single system using the developing technology of distributed system such as Web Service technology, .NET Framework and Visual Studio .NET 2003 etc. The research work also includes the application of this solution to develop information system of Shenzhou market of person with ability, which also confirmed the validity of this solution.To achieve the research purpose, the work is accomplished as follows.First, this paper analyses main distributed object technologies (CORBA, COM/DCOM/COM+ and EJB) as well as J2EE and WINDOWS DNA which support the distributed object technology. By comparison and analysis, it finds out the reasons that result in the difficulty in integration among information systems of the market.Then, this paper analyses the technology system of Web Services deeply, offers the solution to construct the information system platform of the market of human with ability making use of Web Services and solutes the main technological problems such as secure web services , PM-UDDI etc which are encountered during the actualization of construction.In the end, the technology of Web Services is applied to the item of developing the Shenzhou market of human with ability and fulfills the design and implementation of the public web services collection of the system. At the same time, the web subsystem of the Shenzhou market isaccomplished and achieves the mutual integration among systems by utilizing web services collection of information inquiry.
