Design And Implementation Of Online Marking System Based On J2ee,

In recent years, with the rapid development of the network technology, computer technology, digital information technology, image processing technology, the online marking system turned up. The current examination focused on innovation and practical ability of students, subjective examination paper greatly increased in the examination, but the subjective paper marking is subjected to many factors, and it is hard to make sure fairness and impartiality. Online marking system will convert the student's exam papers to digital data, stores them to the corresponding server system, then separating out a single exam subject through cutting and the segmentation of digital information. The teachers marking the paper that displayed in the screen, and conveniently give the score. The system gets the average score according to certain error control principles to avoid inadvertent error score given by a single teacher to ensure the exam's fairness and impartiality.Firstly,This thesis introduces the advantages of marking online system compared to the hand-marking system, analyses the current situation of Online Marking System in home. Put forwards the necessity of developing the marking online system. Then researches the system requirements, system modules, business process and structure of marking online system, analyses and compares the existing software developing modules and technologies, at last selects the JSF+Spring+Hibernate as a framework for online marking system. Designs the system framework, module functions and system database and Implements the some modules of online marking system, for example, the implementation of exam management module, system management module. Finally to ensure the safety and reliability of data, the server used RAID10 hard disk image segmentation and technical processing technology, and implements the load balancer and failover by configuring the server as a cluster.The system in accordance with this article design has already applied to the actual work, and is received favorable comment from users. Actions speak louder than words, this system has very fine practicability, high efficiency, and easy use, at the same time, it has opening, flexibility and expansibility, and it can adapt to the demand of constant perfection and development.
