Based On The Net Network Test System Design And Realization

Network examination has a good prospect along with the rapid development of computer technology and continuous improvement of Chinese educational informationization.Traditional systems of network examination are based on C/S mode,but those systems are hard to install, maintain,transplant and have many other problems.This thesis constructed a system of network examination which is based on Web on this condition.At the beginning,the paper introduced the research background, current situation at home and abroad,significance and content of this research,expanded rationale about related systems of network examination,discussed.NET technology,ensured systemic design of three-tier model.Then analysed and finished total functional design to needs,chose appropriate database system,designed datasheet and stored procedure.This thesis primarily analysed several key issues occuring in the achievement procession of the system:Preferentially contented the important restriction of generating paper,used an algorithm of generating paper based on improved KP(Knapsack Problem)to increased the successful ratio;Contraposed the differentias of objective questions and subjective questions,objective questions adopted precise matching,and subjective questions adopted score point matching and single applicability;Used Ajax to control examination time by server,it improved the veracity of timing and avoided the cheat effectively.The system of network examination carried out in this thesis is based on.NET Framework 2.0.I simplified the exploitation through ObjectDataSource,data binding technique and three-tier model,I optimized systemic capability to provide strong retractility,currency, compatibility and maneuverability,so exploratory value of the system is being elevated.
