Based On The JSP Online Exam System

With the computer and network technology development and popularization of educate information-based is inevitable trend. University opened a lot of distance education, through the computer network of a long distance away from the students for teaching, in this environment; the online examination system also came into being. Online test on behalf of the future examination of the way of reform and development direction, it can improve the examination and office automation level and management level; lower test costs, increasing efficiency, promote the teaching and examination norms unity, push the development that the modern long range educate, make examination more and efficiently, fair, reasonable.At present, most online examination system there can be more or less the defect, such as poor expansibility, poor security, and the method of edit the examination paper is unitary and so on, making it difficult for large-scale formal examination. Aim at this kind of circumstance, this paper introduces a method of JSP-based online Test System Design and Implementation.This article first introduced the research background, system requirements and main research contents of this topic. Then it described the theoretical knowledge and related technologies used in this system in detail, including development tools, systems and structures, workflow, database design, the algorithm of auto group volume, the testing of system, etc. The system uses the structure of B / S framework of three tiers and chooses JSP technology as its development technology, Tomcat as its Web server and SQL Server 2000 as its background database. The client of this system uses browser to complete the operation. It mainly consists of sub-system of administrators, sub-system of teachers and sub-system of students. it has the functions of multi-user online exam at the same time, dynamic random, automatic, user management, performance management, and so on. In this paper, we described the algorithm and computer programmer of the implement method and auto group volume.The topics to complete the design and realization of the test system had been operating normally. The system can interact with users timely and conveniently, improve the efficiency and the level of network education examination and make the system easier to maintain.
