Design And Implementation Of Information Technology Online Examination System

The rapid development of the Internet makes its popularity more and more widely,and the use of computer network technology is more and more extensive.With the followed modern education technology is also constantly developing and progress,and paperless examination is one of the results,more and more popular.On the basis of absorbing the previous development results,this paper consults a large amount of data and obtains theoretical and technical support.Combined with my own practical work,the development and design of information technology discipline paperless examination system.Based on the research background of the subject,this paper introduces the current situation of paperless examination application,puts forward the necessity of development,and expounds the significance of the research.Then the technical support tools of the implementation are briefly summarized.This paper analyzes the problem of intelligent group volume,and through the analysis of the characteristics and adaptation of the three group volume algorithms,the improved genetic algorithm is selected as the group volume algorithm of this system.At the same time,according to the basic design rules of the system,the user's functional requirements and the system's network architecture are analyzed,the system database framework is constructed,and the E-R diagram of the examination system is optimized,as well as the user information table,question information table and other database tables.Based on the general principle of system development,the main modules of the designed online examination system have the functions of sub-role login,group volume management,problem library management,examination management,reading and performance publishing.The final design is based on.NET development,SQL Server 2008 as the system's database platform for information technology online examination system.
