The Design And Realization Of The On-line Examination System

With the rapid development of modern information techonology andinternet techonology, nowadays,there develops distance education in manyuniversities and social institutes whose training and teaching needscomputer network, of which on-line examination system is an economicaland convenient application software as a popular distance education andcomputer education.. However, the design and realization of the systemis still at the exploratory stage.The increasing new entrants makes the university carry a heavyexamination load every semester, which needs the examination system thatcan be adapted to the circumstances. So it must be anxious to get the safe,efficient and reliable examination system.The article has done researches on the system of B/S three layerarchitecture and RBAC model through analysing online examination of thebackground and current situation from home and abroad. On the basis ofthis, It shows us the fine design of the detailed online examinationsystem.This system designs and makes online examination system,using themethod of systems engineering to establish the overall systemarchitecture and application of Windows2003above the operatingsystem,basing on the Microsoft.NET Framework4.0platform and SQL SERVER2005database.With the development of research and development work, thefunction of the system will be more and more perfect.The extension andusing of the online examination system will help change the developmentof the school campus information. The related research paper is mainlydivided into three parts. The first part of the article has a brief introduction aimed at theresearching background of online examination system,researching meaningand the researching condition at home and abroad and presents the mainresearching content of this article.The second part of this article discusses the design of system andimplementation in detail and divids this into three parts.First itintroduced the structure of the system ADO.NET and the platform and thetechnology architecture which the design and practicing is basedon.What’s more,it analyses the requirements of the system,mainlyintroducing the analysis of the aim system,solving problems and thedemand of the system and so on.The final part introduces the design andacomplishment of this system.It is mainly explained and discussed fromthe module design of system, the design of database,and the detaileddesign etc.The third part of the article is summary and prospect.It concludsand summarizes for the experiments achieved in the exploiting andachieving examination system and prospected for the application prospectof the system and development space of the future.
