The Design And Implementation Of Network Examination System Based On Web

With the rapid development of information technology,the computer and Network technology has been greatly popularization and development,we can fully utilize these mature technologies to relize the Online test system.The implementation of Online examination system has very important significance to promote the development of modern education.The Online test system implemented in this paper with C# as the programming language and SQL 2005 as the backend database is based on Visual Studio 2010.By using the ASP.NET technology,this system basically achieved the functions of Online test,including user management,test base management,forming test paper and automatic grading,etc.In the process of realization online examination system,the framework of the system adopt three layers of B/S structure system,which is divided into the presentation layer,the business layer and the data layer.The storage process during data visiting improves the stability of the system.In order to increase the speed of querying data,this system builds the index of common sheets.The importing of Excel file into the test base improving the efficiency of data logging.In order to ensure the safety and stability of the system,we have made some reasonable arrangement on the Internet server,such as different kinds of users have different authority,and users should log in to use relevant functions,and the codes of prohibiting illegal entering and SQL injection is added in each Load event.Practice has proved that the system can solve the problem of automatic scoring and automatic extraction,and meet the B/S structure of the online exam system demand.The system not only has friendly interface but also easy to use,and can meet the needs of medium occupation school online examination.
