Research And Application Of Web Service In Enterprise Informatization

Web Service is a new development model of web application, it has open communication standards and flexibility, interoperability and other characteristics, becomes the platform and main mean of heterogeneous system integration, the basic idea of Web Service is to make the software into service, comply with the corresponding standards, make the different systems cross platform, compatible with each others, with seamless communication and data-sharing capacity. This thesis directed against the research and application of Web Service technology in the enterprise information system to elaborate.At the very beginning, this thesis introduced the source of the subject, the research purpose and significance of the subject, as well as the development and research status of Web Service technology, by summing up and analysizing the basic concept, architecture, protocol stacks and basic skills of Web Service, given the application analysis of Web Service, including the field of application of Web Service, the advantages and restrictions of Web Service.Directing towards the problems of enterprise informatization, combining the technological advantages of Web Service, the thesis designed of an enterprise information system architecture based on Web Service, given detailed design and design principles of each layer. The architecture expands the Web Service technology to the design of system architecture, has reusability, scalability, security, flexibility and other characteristics, overcomes the shortcomings of the traditional distributed technology which cann't adapt the difference of platform, protocol and architecture, provides a new solution for enterprise application systems integration and information interaction between the different enterprises.Finally taking the enterprise information system development of Heilongjiang Gold Mind Technology Co., Ltd as an example, analysized the application of Web Service in the enterprise information, realized all the layers of the enterprise information system architecture based on Web Service, the system take .NET as development platform, use C# language, and the background use SQL Server database management system, adapt B/S structure development mode, and at last elaborated the difficulties and critical points of realization of Web Service.
