| With the rapidly development and popularize of the Intranet/Internet technology, especially its openly system structure, which become the ideal platform in computer application nowadays. Connected Internet technology with the locomotive depot oil plants management will greatly promote the development of locomotive depot oil plants.The locomotive depot oil plants management system based on the Web under the Intranet/Internet network environment has been developed in this paper. Owing to the locomotive depot oil plants supply is a difficult and careful work, the method of the traditional man-power supply is not only a large labor intensity, a bad working conditions, a complicated computing work, a big computing error, the waste to manpower and physical resource, but also the transmission method of oil plants management data information seriously lag, the analysis and processing of the information lacks the objective unification standard, the comprehensive use factor of information resources is low, the systematic capability and the integrity of information material is bad. However, with the characteristic of high effectiveness of Internet, the characteristic of interaction , the locomotive depot oil plants management system based on the Web can achieve some good effects that reduce the labor intensity, improve working conditions, complete the transmission and the processing of the locomotive refuels information fast, accurately and integrally without limit of the region and time.Today there are mainly two kinds of computer network pattern: Client/Server pattern and the Web Browser/Server pattern. The C/S pattern is based on the local area network, and it is an system platform pattern with two layer structures which completed by the client and the server cooperation. There are some merits for using the C/S pattern , such as the strong interaction, the high efficiency, the high speed , the good security. B/S is based on the Internet/Intranet structural model, namely by the browser, the Web server, the database server forms three layer structures. In thisway it greatly simplified the client computer load, reduced the cost and the work load of the system maintenance and the updating, and reduced user's overall cost. In the view of some characteristic the locomotive depot oil plant management system ,sucti as the complex content, a large number of date, the extensive management facet etc. This article gives attention to two merits of the C/S scheme and the B/S scheme, and forms the solution with the mixed style the oil management system structure, through to the rational distribution duty , the client and the server can assign respective handling ability well, satisfies some request that the data and the application program which takes the least resources and the system performance relative most superior.First, from the demand analysis of the locomotive depot oil plants management system, The overall design of the system was analyzed and the system development scheme was chosen in this paper,and introduced the system development environment (software environment, hardware environment and network environment) and some related technology (IRP, the Web technology and ASP technology). Next, it described the information database technology of the locomotive depot oil plants management system detailedly (includes the demand analysis of database design, the design of concept structure and logical structural , the establishment on information resource management foundation standard ,the design of database structure constructs module as well as the realization to the physical structure). Finally,The development and the realization of the system was narrated.The practice of the spot has proven that this system can satisfy completely the needs of the oil plants management,and this system has improved greatly level and efficiency of the oil plants management in the locomotive depots. |
