The Design And Implementation Of Cloud School Marking System Based On B/S

With the improvement of educational informatization,examination papers are no longer confined to paper papers,marking papers are no longer confined to manual marking.Cloud school marking is a data cloud storage intelligent marking method based on the Internet platform.It can provide online marking anytime,anywhere,marking more freely,and the cloud collation and storage of test data,storage longer,easy to find.In addition,the cloud proofreading can solve the subjective problem marking error and marking link error,but also can effectively evaluate the level of marking teachers.Therefore,it can improve the speed and quality of grading comprehensively,and promote the fair evaluation of teaching and learning quality through valuable data analysis.It also has important guidin g significance and application value to promote the fairness of examination.Based on the investigation of the existing cloud marking system,a cloud marking system based on B / S mode is established.Specifically,the main research work in this paper is as follows:Requirement analysis and design of cloud marking system.The demand for the design and implementation of cloud based marking system based on BS is analyzed in detail.Based on the business process,functional requirements and non-functional requirements of the system,a comprehensive analysis of the BS-based cloud marking system construction necessity,the system's main functions and non-functional needs.And the overall system architecture is designed,based on the SSI framework,Struts framework,Spring framework,Spring MVC framework and iBatis framework,as well as database technology related functions of the system design,the system has good scalability,while the system at the beginning of the design to take full account of the system design and database design,making The system has high reliability.Implementation and test of cloud marking system.Using the Java environment of JDK7,Eclipse V3.9 development tools,MySql 6.0 database,Jboss server software and so on,the various functional modules of the system are implemented,including system management,school management,examination management,marking tasks,data statistics,score analysis,making answer cards and other functions.Moreover,a detailed screenshot is given.LoadRunner,a performance testing tool,simulates the repeated execution and running of test cases by users,evaluates the current performance of the system according to the test results,finds out the performance bottleneck of the system,and puts forward a reasonable rectification scheme.
