Research On Application Data Delegation Interface Platform Of Heterogeneous System Based On Web Services

In order to suit the unceasing-changing business needs, and support the sell tactics and respond to the market needs quickly, and help enterprises depended on the information strategy to survive in the market, and eliminate the problem of information sharing, so, the paper build a platform which is called Application Data Center to help them handle the complicated business and work, and help enterprises to strengthen their competition.The aim of this paper's design is to realize all kinds of heterogeneous systems or platforms to communicate each other and work well through internet programing technology, this platform can support an united business interface for heterogeneous systems, and it can help the heterogeneous systems to realize the operation of business handling program in each other, and build an enterprise level's information management platform to realize the intergration of enterprises and eliminate the problem of information sharing.The designing method this paper used is based on the analysis of the widely used enterprise application's architecture which is based on middleware and previous researches and technology, the paper proposed a method based on service-oriented architecture SOA's core technology Web Services to design and realize system.The realization of this system can be expressed as following:On the aspect of transmission data format, the paper designed the data format based on the XML criterion specification, and replaced the particular data format based on middleware.In the process of data transmission, after the messages were handled by the platform, the paper designed and realized the method using SOAP protocol to package the XML format messages, and SOAP protocol is a bottom layer communication protocol supported by the overwhelming majority of systems, the method this paper used replaced the middleware's bottom layer's communication protocols.To the application transimission protocols, through using RPC model of Web Services, the system used the UDDI and WSDL specification to publish the web services, and finally use the HTTP protocol for the data transmission, and the method it used replaced the particular transmission protocol based on middleware.To the software designing mode, the paper is created based on the thoughts of the software designing theory, the system also realized the software designing mode, including Abstract Factory, Singleton mode, and these modes improved the security and reusability of system's codes.In short, through the testing and running method, the system indicated that it realized the application programs to carry out the data transmission and communcation among the heterogeneous systems, and it is fully based on the standard criterion, and the platform integrated the isolated system into a whole system. The method this paper used realized the information sharing among the heterogeneous system, and it had good effect, after all, the system this paper realized combined the available whole solutions and the specific realization schema.
