Research And Implement On Railway Stations Exercise System Based On Data Warehouse

With the development of China railway, the application of information technology has already become one of the most key tasks to promote railway technology development. Railway station plays the main carrier in railway transport production, the state of which will infect the efficiency and safety of railway transportation. So it's very necessary to adapt the situation for railway stations to improve the locomotive operation and management level.Based on the problem of railway stations information process, this paper proposed railway stations exercise system data warehouse technology applications. Discussed the basic concepts of data warehousing, data structure and data warehouse design methods and steps, focusing on approach and model of create a data warehouse. Design data warehouse from four different levels: the data storage needs analysis, data warehouse concept model design, data storage logic model, and data warehouse physical model design.This paper mainly study on analyzing and designing of railway stations exercise system. The paper makes out the optimized system operation flow and data flow according to the user requirements analysis, and emphasis on designing the total structure, function modules, network structure and database of the system. Furthermore, the paper design and realize management and monitor system of railway stations exercise in details and research on the key technologies involved in system which contain achieve in GDI+ graphics capability, achieve in the local area network sharing-picture within serialization, GDI+ dual-use technology to improve the graphics buffer efficiency, designing of system data security and applications of computer system of interlocking. The application of the system not only improves the efficiency of railway stations exercise but also promotes the management level.
