Based On. Net-water Treatment Management Information Systems Design

In this thesis, a real management information system of SiTong Environment Corporationis designed and realized. In the process of developing this system, we pay special attention to thenew technology and the new tools. It uses the Microsoft's newest framework VisualStudio.NET,the C#.NET,ASP.NET and ADO.NET technology,and also combine with SQLServer 2000 database, so it make the software's frame more reasonable and more convenient, andalso improve the performance of the whole software. According to the process of softwareengineer, this article expatiate the whole system in terms of the key technology,the wholedesign,the database design and the page layout design. In the key technology section, this thesisdescribes the .NET framework, the ASP.Net technology and the ADO.Net data accessingtechnology in details. The whole design includes the system's framework,the composing ofsystem's software the hardware and the local network configuration. While selecting the mode ofthe system, the advantage and disadvantage of the popular C/S and B/S mode is analysized inthis thesis, and then the B/S mode is choosed in the system. The three-layout structure, whichmakes the software have the character of clear frame and easy maintenance, is adopted in thesoftware designing process. In the database design section, it give the database design and thetable design, also the relationship of tables.The use of storage process improve the accessingcapability a lot,it is easy for the further develop.In the security aspect,the paper mainly describethe user's certification identification, and how to give the user some purview according to itscertification. We register the user's certification in the session, before it lose,the user can visitsome modes and hand with some dates according to user's purview. The page layout designmainly describe the CSS technology using in the appearance design, and also describe the pagelayout and function designs of the sub modes. It givethe program. For the limits of the length, it is not possible for the presentation of everymodes, but the main design flow and the ways are expressed in details. I hope this paper cangive some help to the other management information system's design.
