Design Of ASP. NET-Based Information Management System For Experiment Center

With the gradual promotion of college teaching reform, experimental teaching management scope has been expanding constantly and includes a series of elements, such as experiment rooms, courses, experiments, resource sharing and so on. Traditional management model is no longer able to solve such complicated experimental teaching management work. A new web-based experiment teaching management system is needed which has perfect function, high level of data sharing and easy extension. This new system is very convenient for students to get information and select experiments and can improve teaching efficiency, increase the extent of source sharing, reduce experiment management staff and teachers'workload and better ensure its exemplifying role.To improve the information management level, a new platform has been developed by adopting ASP.NET 3.5 and SQL SERVER 2008 on the basis of sufficient investigation and construction experience which the National Experiment Center of Mechanical Basis at Southwest Jiabtong University has got in recent years. The system structure consists of client layer, application logic layer and database layer, featuring easy extension, easy maintenance, openness, intellectualization, high safety and reliability, etc.Firstly, the development environment and theories to design and develop an information-based system for experiment center are introduced in detail, including ASP.NET framework, ASP.NET AJADX, ADO.NET technology and relational database technology.Secondly, structure design and system analysis including feasibility analysis and requirement analysis are described in brief. The requirement analysis provides goal and direction for the design and implementation of the system while the structure design presents a general idea of B/S model to develop the system and its purpose.Thirdly, functional modules design and database design are introduced in the system design section. Since a successful information system depends on the quality of database design, the database design rules and its design are discussed in detail.Finally, the implementation methods of the management system are elaborated, including the application of ASP.NET and JavaScript language to develop automatic interval refresh of center pictures of the front interface, Ajax to fulfill non-refresh linkage, C# to develop the back stage code and achieve the data importation. The implementation procedure above fully displays the high-efficiency superiority of ASP.NET platform to develop information system projects and supplies a suite of development framework for system based on the B/S model on the.NET platform. By constantly debugging, trial operation and improvement, the system has been formally put into use and obtained good application effect which has improved the information management level of the Experiment Center.
