Research And Realization About The Publishment And Realization Of WEB Service In Railway Information System

After decades of years of development and construction,the Chinese railway information on each department has made great achievements.However,due to a lack of unified information construction planning,the interoperability of various business systems and interoperability is not very well.Much information is difficult to be used for other systems,resulting in a waste of information resources.Therefore the railway information resources sharing and utilization has an important significance for the railway's development by leaps and bounds.SOA(Service Oriented Architecture) is an effective solution to the heterogeneity of the problems arising from the structure of the system.The idea is to provide a unified interface,through the release of service,service discovery and service invocation mechanisms such as applications for other services.Web Services technology-based system to provide technical support,Web Service technology make system based on the realization of SOA possible.In this paper,we investigate the construction of the railway information,then,analysis the problems of railway information sharing.Through the research of Web Service and related technology,we make out the railway information sharing platform technology architecture.At the end,we verify this paper's program from the construction and the integration of the railway services by web service.
