Design And Implementation Of Online Judge System

This system used for classroom test,reduce transceiver papers and papers of the time,and the results show that the correct rate of each question,let the teacher in view of the weak point of students' knowledge,has a role in Teaching.The system uses the B/S structure of the classic,strictly follow the B/S structure of the development concept,easy update and use.In the design phase,the software as a key availability and easy.To improve the user experience,part of the realization of the use of asynchronous submission,which greatly shortens the time system.According to the papers in the process the workload and dense,system gave emphasis to solve.At the time of writing code,the use of the factory,the singleton design pattern,improve code efficiency and reuse rate.This design is the application of SSH2(i.e.,the most popular Struts2,Spring,Hibernate three frames)to realize online evaluation system background frame and front Jquery framework.Using MyEclipse as a development tool,combined with Oracle database,the use of Java language,using JSP,Servlet,JDBC etc.In view of the persistence layer,business layer,control layer for unified management,to enhance the expansibility of the system.To realize the online evaluation system by using the theory and technology.
