Design And Realization Of Online Examination System Based On WEB Framework

The development of information technology is a promotion to the diversification ofeducation methods. Without geographical and time constraints, the distance education issure to be more and more popular. It is more convenience to online students, and willhelp make a life-long self-study system, which will directly help improve our citizen’sknowledge level, make full use of our country’s educational resources, and also cut thecost of education; it is a project of letting every citizen to enjoy the right to be educated.This paper first studies the current situation of exam information, and finds out theproblems of exam information, then on the basis of analysis of advanced technology,this paper points out the minds of exam information service system. This paper givesout the basis problem to be solved. Then this paper introduces the hardware andsoftware environment for system design and makes a comprehensive analysis of allkinds of influence points, such as potential user groups, registered users, click-throughrate, download traffic and input costs etc. Then this paper makes a preliminary design ofthe hardware and software system environment based on the B/S structure, which isdeveloped by ASP.NET technology and takes the Windows Server2008operatingsystem as the server takes the Oracle10g as database. At the same time, on this basis ofsummary and review of the existing research work, this paper simply introduces thenext step work about the research content and the work need to do, and makespreliminary thoughts and prospects of the exam information foreground. And then thispaper details the factual situation, finds out the key needs, finally gives out the basicfunction module and these system functions and operational flow charts, what is more,this paper also finishes the program flow diagram. Finally this paper finishes all thesystem function modules we need to design, and analysis the key technologies in systemrealization such as data graphics display, historical data playback, data queryoptimization, and gives the concrete illustrations and the realization code. what is more,in order to check the performance of the whole system, a test is carried out. The result isanalyzed and some points needed to be improved are also mentioned.In all, this paper makes full use of the internet to provide a student centered online learning environment, which makes teachers’ teaching experience into the learningprocess in learn navigation methods, make students the subject of study, realizes theteaching mode based on students’ individual ability, and achieves good results.
