Development And Application Of An Online Examination System For Vocational Colleges Based On ASP

The examination is a necessary work of school, is also the main task of many examination organizations.With the fast fierce development of the computer technique and the network technique,The drawbacks of the traditional ways of examination outstandingly, network's online examination mode gets into people's visual field gradually.Traditional examination mode has been replaced by no paper examination,such as make out questions, supervise, grade point, Statistics score etc.It on the clients configuration request is extremely simple, make examination is not subject to regional restrictions. A comprehensive on-line examination system, can realize the automatic generation, examination paper topic of submission, performance reviews, etc. As long as the form a complete set of maturity database, it can achieve test automation. Thus, teachers just to elaborate design topic carefully, maintenance database, not organize an exam and marking the examination papers, thereby significantly reducing the teachers' burden, its economy is considerable.Therefore, online examination system is a very active application fields that one of computer network technique in recent years, also one of the most important research project in Vocational Colleges. The online examination system is being taken more seriously by people for its economize on manpower and material and funds, raises an examination efficiency, optimization management in teaching, improving the teaching quality. With online examination system extensively applied, auxiliary anti-cheating function continuously introducing, such as: network monitoring function, random a coil, subject mix, and other functions,the system is exactly according to this purpose, carry on design and development, discover problems and solve them in the test, gradually adapt to the need of a modern Vocational Colleges.The system based on B/S designed pattern, with the Web Server + the database system + the ASP for the software development technologies and developed the online examination system that is applicable to the Vocational Colleges's software engineering.The candidates complete to examine whole processeses in client browser,and server cmplete to all system designs, development, optimization etc. Also,it can carry on the management of long range system. This paper first discusses the online examination system the research background of home and abroad research status, and clarifies the online examination system development trend and significance. In addition, analyses the current examination system commonly existing problems, and puts forward the next research direction. Secondly, introduces the development of the system applied by related technologies, including dynamic web technology works, ASP dynamic web technology and operating system environment. Then from the system demand analysis, Detailed introduces the system of three big function modules, is a composed of User Login (include the functions, such as student register Candidates and identity logging,teacher identity logging and managing person identity logging),a composed of online examination (include the password modification of Candidates, on-line answer and online search result ), a composed of the system managers(include the password modification, category management and database management , Marking examination papers, comprehensive functionsand managers management).Thirdly,testing the system, analyse and solve problems.System design of again perfect will also have it shortage of place, developing a system isn't a purpose and own a suitable examination system of the college is end target.Combine the problem for appearing, end, we propose an improvement aimed at the Datagram congestion and Anti-cheating means.System development after, we put the research has focused on how to solve the Datagram congestion and anti-cheating means on the question of how to implement. This is one of the paper's characteristic, combining data congestion problems in existing hardware resources, this paper on the basis of shunt technology and replacement respectively from the Angle of platform was discussed. In addition, in order to solve the students cheating in the exam questions, the paper put forward respectively based on peripheral solutions, based on the Internet solutions and lan-based solutions, and provides a very effective exam anti-cheating system. In the implementation of the colleges can be seen in its method is very effective.This system function complete, website friendly interface, navigation is clear, simple operation, easy maintenance. The article puts forward the improvement scheme effective and reasonable, accords with modern vocational colleges demand, has certain application prospect.
