Research And Implement On The Enterprise Management Information System

As an important management method in Modern Corporation, the information management system has been used in every walk of life. The concept of digital corporation management is gradually accepted overseas. The database management of the resource and the products is popular in these enterprises. Some corporations may study and develop in a long term. According to the difference of the using environments, the system includes the plane database based on FoxBASE or FoxPro and the distributed database based on the frame of C/S or B/S. And the expense of exploitation for large system is very expensive. As a whole, the development of the foreign corporation management system is gradually mature. But in our country, the discussing and implement of the ERP and PDM is being taken in big corporations. But the succeeding examples appear severally, and some only integrate and change the foreign products in their works. The major obstacle is the expensive cost in studying the database management system in domestic corporations. Being the blurry demand and the few cultivation of the user, the studying system comes to an untimely end.Based on the design of the enterprise information management system about JIANAN corporation of the ZHUZHOU Water Company, this paper discusses the theory and methods of the enterprise management system.

And the system is obligated to provide enough resources and interfaces for upgrade in the future. The major works of the paper include:1. Research the method of associating XP and UML, and refine the manager of software development, that not only ensures the enough intercommunion with clients, but also guarantees the relative standard of the program model;2. The application of the modeling software of the database is studied. The problem of the represent and realization of complex connection in big corporation database is solved. And the opening interface is presented and realized between many standard data formats for exchanging in popular industry;3. The reasonable dispose of the 3-tiers in corporation is studied and implemented. Many optimizing methods of software are realized under 3-tiers. UI is designed which is agile and convenient. Several special application of corporation is realized (for example, the testing and analysis module of the mechanical abrasion, the module of the Remote-Task information manager and the module of the feedback manager of support water etc.).This paper is put forward a fitter way to use software project management for architecture corporation's MIS, and valuable to the middle corporations in realizing and studying the information management system, and is practicable in the application field of studying the 3-tiers, oracle application and graphical treatment etc.
