The Design And Implementation Of A Car Management Information System

Car Management Information System is a management system used to improve efficiency of car management and maintenance. This system is established in the real project requirement of SD Postal, Beijing Chenxi and Shanghai Yinhang and developed by advanced design methods and technologies. The purpose is to enhance the supervise level of the whole car management work by procedure control.This paper works from the requirement analysis, finished setting up the system architecture and designing it in detail. In the end, the system has been implemented as a management information system based on B/S structure, including six subsystems named Car basement information set, driver management, car dispatch, dynamic state query, car maintenance and information query.In this paper, the system development background has been discussed, as well as current research status of car management system on internet and web application system based B/S structure. Then problems to be solved have been clarified by describing aspect of system requirement analysis. During the course of system design, the work began with architecture design. The technology architecture , function architecture are built at first. Then the system static modeling, dynamic modeling and the design procedure of database structure have been discussed in detail. At last, several important problems encountered during the implement have been analyzed.Effective solutions to those problems encountered during the procedure of requirement analysis, design and implement have been put forward in this article. All those supply powerful examples for car management system development.The key problems solved in this paper are as follows:First, stratified MVC is development model which support object-oriented method. In this paper, stratified MVC is used to complete the system design and implement. Then the user requirement can be fully understand and the system can be optimized step by step.Second, in so many solutions of building B/S structure, J2EE and SPRING becomes the most favorable because of the excellence it has been putted up when develop Web application. According to the user's requirement and the characteristic of this system, I integrate J2EE with SPRING framework.Persistence layer architecture JNDI is used to reduce the cost and improve the maintenance and expansibility.Third, in this paper the database structure design, one of key problem in the MIS development, begin with the Conception model design, and then the object-oriented model, at last the physical model is built. This kind of method makes the database design more reasonable.Fourth, effective methods are put forward to solve the problems often encountered in the system implement, such as car state dynamic query, page refresh slowly, input information inclined by people and car apply confusion.The system has been implemented perfectly in Shandong postal OA system and Beijing chenxi project.It enhanced car management effective in the enterprise.
