Researching And Developing Of Dot Net Based On Online-Exam System

With the application in the educational field of the information technology, the traditional examination method faces an important change. as a kind of new-type examination form the computer network based online exam system has gained more and more attentions. It has overcome the limitation on the time and space of traditional teaching and became the important motive force of improving educational pattern of the society.At the present time, online exam system has greatly reinforce the means of modern test. Comparing to the traditional test, is cost saving and laborsaving in organizing test, reading test paper and scoring, and it break through the limited of time and spatial. The use of computer in various exam not only save the resources, but also increase the veracity and objectivity of scoring, and that it improvethe efficiency of test work. Development the dynamic of remote education. So that, This paper studies a design and project of online exam system based on .NET and ASP.NET.This article introduces the development course in detail using a real system as an example. The last chapter is the summary of this paper. The system adopts three-layer structure in pure B/S mode. A large number of the user controlling components of the .NET framework are used in code, which has raised the reusing rate of the code. It analyzes the system with the use case picture in UML during the course of requirement analysis and divides the function module and provides the important workflow in the system. The article provides the E-R models of the data base and logic structure of some important tables. It also introduces the concrete implementations of important functions and gives the actual operation results in detail. Finally it summarizes the subject and puts forward the goal of follow-up study of the subject.
