The Research And Application Of Network Experiment Teaching System Model Based On UML

With the development of modern technology concerning network education, the researchers are paying much attention to the issue of how to research and establish an all-round, effective, safe system of teaching and management of professional experiment in a network environment in recent years. The experiment teaching and management system combined with the teaching and management of experiment of colleges, is able to solve a series of problems, which have confused the laboratorial managers for a long time, and realizes the modernization of experiment teaching and management.This thesis presents a model of experiment teaching system. It establishes many type of models like use case model, static structure model, dynamic model, data model and physical model by using UML(Unified Modeling Language), and designs the DataBase of system model on the basis of these models. Then the thesis gives an analysis of the security of Windows, IIS(Internet Information Server), .NET, ASP(Active Server Page).NET and DataBase, and discusses the security of data storage in particular. A set of security mechanism which goes with this system model is then developed after research, and the archetype system of experiment teaching is realized by using ASP.NET technology and DataBase technology of ADO(Active Data Object).NET. The functions of reservation, arrangement, teaching and management of this archetype system can not only help managers of laboratories to improve the efficiency and quality of the management, and realize the modernization of the management, but also can provide a good and open professional experiment teaching and exchange environment.The archetype system provides a universal system framework so as to assist the experiment teaching, and resolve the separation and disconnection of experiment teaching systems of colleges. The archetype system may add and modify some functions flexibly in order to adapt to the actual features of experiment teaching in colleges. In addition, the security mechanism can ensure the security of the system efficiently in all aspects, especially the class base with such developed functions as encryption and decryption of data storage can protect some sensitive and important datas in the system perfectly.
