Design And Implementation Of Online Examination System

In recent years, the application of computer software in all walks of life has become more and more popular, and in education and teaching is no exception, computer and computer network information technology has been widely used, in which online examination system has many successful cases. Online examination system based on computer can not only improve the speed of online examination, but also in computer remote control is more convenient to operate, and can save the cost of human and financial resources. Because it reduces the participation of people, so the fairness of the exam can be well guaranteed. From examination to papers to evaluation, can use this system to complete, the online examination system as a new exam mode replaced the original paper-based exam mode, new computer scoring substitute artificial scoring method. Once launched, it should be widely used.Online examination system development is based on Visual Studio Microsoft 2008 as the system development platform, the use of advanced C#.NET technology to build the front page, the background database technology to use the Server SQL 2008, the application is simple, and the system is safe, stable performance.The design of online examination system adopts the structured design method of top-down, layer by layer decomposition. System design according to the requirements of the system analysis and the actual situation of the organization of the overall structure of the new system design. The system is divided into the test management subsystem, the examination and the score management subsystem and the basic information management subsystem. The sub system is divided into several functional modules, each layer is divided into a single module until each module is relatively independent, the function of a single procedure. Online examination system including test management, examination and performance management and basic information management subsystem. Including the management of papers and questions, the examination and the results management include the examination management and performance management, information management, information management and student information management.Twenty-first Century is the information society, the application of data information has entered the stage of mass service. Examination as the most direct embodiment of the information society in people’s knowledge level of a way, is currently the most widely used form of one. The online examination system, which has no paper, network and automation, has far-reaching practical significance and practical value. At present, the rapid development of information technology, especially the rise of network technology, makes the examination information and automation possible. Three layer structure appear provides a good system architecture for designing, organizing and answer, so as to realize the unified management of item bank, dynamic test, automatic sentenced to roll, greatly saves manpower and material resources, improves the efficiency.
