Design And Implementation Of Online Examination System

With the innovation of educational thought and the rapid development of the computer network technology, informationization of education is an inevitable trend. The examination as a standard of education evaluation has also been experiencing paperless and network leap. And the paperless testing system is becoming increasingly valued due to its object, fairness, security and accuracy. The online examination system based on Web technology has been an important application of Internet, and there are important academic and realistic meanings to the research of this direction.The algorithm of generating test paper is a hard point during the implementation of the system. In the analysis of stochastic selection law and the recollection trial method group function insufficiency and in the shortcoming foundation, the paper proposes and realizes a new method of hybrid solution algorithm. In the simulated annealing algorithm introduction genetic algorithms, the new algorithm has improved the algorithm search space greatly, at the same time avoiding the genetic algorithms being easy to fall into the partial minimum flaw.Experimental results show that the new algorithm moved up the speed and success ratio for intelligent test paper.Considering the requirement and characteristics of the online examination system in higher vocational institute, the performance requirement, data requirement and function requirement of the online examination system based on campus network are analyzed. Then, the overall structure, the system functions, the secure architecture, the database of the online examination system are designed.Based on the campus network, the whole system uses the advanced and stable JavaEE software architecture. These technologies improve the system reliability, stability and performance.Based on the research of struts spring and hibernate'integration, a new method in web development is presented.That is while using Struts developed presentation layer, using spring developed business logic layer, hibernate is used to configure endurance layer. At last, the thesis completes the implementation of on-line examination system. The system uses SSH framework which is based on struts spring and hibernate, it improves the developing efficiency and speed and reduces the complexity of system maintenance. Furthermore, some revolutions are given to somes difficulties and system security.This online examination system has been running well in Loudi Vocational &Technical College, and the result is satisfactory.
