Abstract aperless exam is an important symbol of modern education for this kind of exam make the result more reasonable, more just, and release human resource. The online exam system of university, usually uses the C/S MIS architecture, or based web use B/S architecture. In the exam system of C/S architecture, where the papers are stored in the remote Server and the Client must set up the exam application and configure the database, we must set up and configure the Client every time when do exam. However, the exam system using the B/S architecture can implement thin Client by combining the Management Information System. As system maintenance is only necessary at the sever end, our developed exam system is based on B/S architecture. WEB application software is either of C/S or B/S modes. The main disadvantage of the previous mode is the trouble of maintenance and update, and thus the charge is higher; the B/S architecture is composed of Browser and Server. In this architecture, the user interface is just implemented on WWW Browser, a little part of the transactions is implemented in Browser, and the main part of transactions is implemented in Server. So the load of Client is reduced, and thus reduce the cost of maintenance and update, so as the whole cost.
This graduate project is about the exam system based on java and B/S architecture. It has implemented the basic function needed by the student, teacher and administrator. In this B/S architecture project, students login the system through web, and commit the answers in real-time. The system can judge the paper and save the result, statistic, manage the points; help the teacher to find the problem in teaching. It allows any student which is authorized to subscribe to exam and gain the result at anytime or anywhere, and reduce the workload of the teacher for giving question, invigilation and judging paper.
