Design And Realization Of Information System Of Managing School Rolls In Higher Schools Based On .Net Technology

With the popularization of Internet and the increasing demand for network application such as e-business, distance education and the corresponding requirement of advanced technology, network database or web database, as a data warehouse, has become an important research topic on application system based on the web.By analyzing the application system of distributed web and discussing the systematic structure of Web Servers, in light of the respective features and advantages of Sun company's J2EE and Microsoft company's net development platform, this paper is intended to design a multi-structural information system of managing school roll in higher schools based on .Net technology after a series of demand analysis, outline design and master design of the management of school rolls in higher schools by using the Visual Studio .Net technology and the UML analysis method.In order to establish the systematic structure of Web Serves and enhance reusability of the software and safety of application system, this paper lays emphasis on researching and analyzing technology of loginning, data enciphering, database connection visiting, ensuring database safety, defending Web attack and reserving data to avoid any disaster and then gives some better corresponding solutions.Given the fact that ensuring safety in visiting database is a complicated issue, this paper develops and designs a set of business logics supporting various frequently-used databases and applicable to any Web system by adopting the multi-structural form and ASP.NET technology.In addition, with a view to ensuring safety of the database content and operation, this paper designs business logic applicable to symmetrical enciphering (enciphering and deciphering) and irregular enciphering ( ensuring cipher safety and avoiding secret divulging )and business logic used to defend Web attack in the form of DLL suitable to any Web and any application system or program.In light of man-made and natural factors attributable to data safety, this paper especially researches some technology for ensuring data immune to any disaster and consequently finds an economic, safe and feasible program for avoiding any data disaster. This program is conducive to ensuring data safety as well as system restoration within the shortest time, thus minimizing the loss.Through developing and practicing information system of managing school rolls in higher schools and researching and analyzing the multi-structural structure of Web Servers, this paper does a beneficial exploration into distance maintenance of the multi-structural network database based on Web technology.
