Design And Implementation Of Data Exchange System Based On XML Technology

Data exchange is now an important factor affecting the development of enterprise informatization management.The purpose is to completely share the different data in the heterogeneous environment(loose coupling,different data format,cross-platform,and cross-regional distributed environment),to use resources rationally and scientifically,to enhance the integrated performance of the entire information system continuously,to refine the data channel,and to improve the data flow rate between the information system.However,the applications of data exchange technology reveal many problems in the heterogeneous environment,such as the large coupling,high cost and the complex implementation,and so on.With the emergence of XML and Web services technology,a new way to achieve data exchange has came out.This paper aims at the complete exchange of data in heterogeneous environment,using the new XML and Web service technology to design a common heterogeneous data exchange system.Based on the current data of a certain enterprise in Hunan Province,this study analyzes and compares the prevalent technology of data exchange.Through the defects of the original technology including the lack of uniform standard,the strong dependence,and the large degree of coupling between systems,this paper proposes the goal of completing data exchange in heterogeneous environments by using of XML and Web services.Ground on the detailed analysis of common data exchange patterns and topological structure,a heterogeneous data exchange solution based on XML and Web services has been designed.Not only does this research paper plan minutely for the architecture of the framework,the working process,and the function of each module,but also elucidate the reflection between XML documents(or between documents and database),the extraction of XML Schemas,the transmission and receiving of XML documents,the encapsulation and analysis of XML documents,among other design and implementation of crucial module.Besides,this study also analyzes the security problems and offers solutions.Finally,the test results of data exchange system based on XML technology indicate that the system fully satisfies the function and security requirement of the enterprise in Hunan Province.After the trial operation,the system solved a series of problems brought about by the heterogeneous data,greatly improving the efficiency of employees.
