The Research And Application Of Web Service Technology In Data Exchange System Based On .NET

With the rapid development of network technology,applications based on the internet have been more and more and accepted by more and more people.Internet has become the center for the exhibition and exchange of all kinds of informations. When faced to those heterogeneous data resources based on different platform and system,it is a question which needs to solve in computer research area that how to proper organize applications and use resources on the Internet.The goal of data exchanging system lies in the realization of the sharing of data information and proper organization of resources.Web Service technology can provide a solution based on XML in all technologies of realizing data exchange system.As a technical standard of data exchange,with its specialities of structured,extensible and independent of platforms, XML make possible for web service to provide limitless connection.XML and Web Service technology provide a perfect solution which can realize data exchange system based on Internet.As a new technology and generalized by Microsoft,.NET designed as a Web Service platform,provide strong support for Web Service development.This paper is intended to probe into how to use Web Service and.NET technology to organize resource on the Internet.Following an introduction of such technologies as Web Service,XML and some other related technologies is an analysis of the developing platform of Web development,the.NET framework and ASP.NET programming technology,which are the base of present paper.In the last part of the paper,a Web Service based dynamic data exchange system data model is designed and developed with the technologies as metioned above.The main reaserch results of this paper are as follows:(1)Research in Web Service development model in.NET and give a sample of application.(2)General development planning and system architecture have been proposed based on an actually company project.The system models are described with UML.(3)Provide a Web Service based system model after comparing the exsiting technologies of resolve the problem of system data exchange.(4)Design the data exchange method using Web Service technology and give the detailed realizing process.This system implement proper organization and sharing of resource on the Internet by using XML Schema define data standard and using SOAP, HTTP protocol to exchange transport.
