Design And Implementation Of Online Examination System Based On Java

Computer technology has not applied to the examination, the organization at least have to go through a five-step test, and that of the candidates to test artificial markers, the results of assessment and examination papers. The workload of teachers will be growing, and its work would be a very cumbersome and error-prone things very clearly the traditional way of examinations has been unable to meet the needs of modern examinations. With the rapid development of computer applications, application constantly expanding, such as teaching and the emergence of virtual universities and so on, and these applications are gradually and families. People urgently require the use of these technologies for grading examinations, so as to reduce the burden on teachers and improve work efficiency, and at the same time improving the quality of the examination, so that the examination tends to be more civil, objective, and inspire students to learn more interest. For example, many international famous computer company run by the vast majority of the various certification exams in this manner. Therefore, the students of Web-based online examination system of great significance.Java language itself because of the openness of the system,as well as simple grammar,extensive domestic Java technology applications.Web-based application of key technologies and content mainly concentrated in the data access,data format conversion,logic control, data transmission,data such as that,and those are the advantages of Java,thus in the development of the schools through network connections a browser/server students use online examination system of projects,we have chosen the Java language and technology as a development platform.This paper first introduced the appearance of network test and analyzed the research significance of test system.It carried on the comparison to the domestic and foreign present researching situation about network test system.It also elaborated the network test’s essential target as well as its characteristic.This paper provides an online examination system with simple and useful functions.The system is mainly for public institutions and enterprises to assist their daily training and assessment, and has a good prospect of application for large-scale examinatio.The users using this system can add, modify and inquire such test questions as judgement, filling, choosing and discussion, nd manually or automatically group test papers, so as to realize the true no-paper examination. Any authenticated student is able to test himself at any time and in any place, and the system will then show him the evaluation of accomplishment. This system helps minimize the teachers’ repective tasks as setting grouping and grading papers.The paper also applies such technologies as J2 EE,MVC and three-tier structure to develop a small system based on B/S architecture.
