Uml-based Student Management Information System Design And Realization

Student's information management is a key to manage a school which involves student status records, grade records, teacher management and course management and so on. It tends to adopt computer information technology to manage student information which will provides exact student information in time and raise the management's work efficiency.This paper is based on the requirements of the Shandong labor vocation technical college in student information management. The college's organization structure and student management flow is analyzed. It provides this system with a detailed analysis and design based on the basic terms and methods of Unified Modeling Language. 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 mufti-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.This system uses the SQL Server 2000 of the Microsoft do the backstage database server, carry out under development environments of the Visual Studio.NET 2003. Under the frame of.NET, adopt the modern OOP C# programming language, the ASP.NET active server page programming technique, the ADO.NET database object access model advanced technique, insure the system establishment under the forerunner's terrace management, there is longer life cycle.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 mufti-structural form and ASP.NET technology.The software of this system is based on B/S architecture. The system can run on the TCP/IP network and client software runs on IE explorer. The gearing of the software carries to carry on in the server only, the customer carried to carry out " zero" gearings; The system frame provides each module the standard connection, all two levels of tables of contents may nimbly have custom-made, cause the system function to be allowed further to expand; Registers the diary,the operation diary is advantageous for the prompt discovery system security hidden danger; Moreover, the system uses take the role as the central security model. This model use role separated the module and the user, enhanced the system jurisdiction management efficiency.It is indicated in practice that using the technique of UML modeling, Reusing of Software and the method of RUP to develop software system ,can greatly improve the efficiency of software development and the quality of software.
