Based On The J2ee Platform For The Online Examination System Design And Implementation

Education technology innovation thanks to the rapid development of network,evaluation of the learning effect also becomes the modern network education is of vitalimportance to the content. One of the main evaluation means is the exam, teachingevaluation and examination accuracy and objectivity of the normative, scientific,reasonable is closely related to the organization and management of, and also indirectlyto teaching quality have to the quality of the profound influence. Through the Internet orLAN for some of the mains of the paperless examination in order to achieve the exammanagement, That is online platform of the exam management function. The schoolorganization management and the examinee is very convenient, especially suiblank forlarge scope exam.That thesis takes the university "based on J2EE of university on-line examinationsystem" project, based on the careful study at home and abroad and on-line examinationsystem, the problems of the access to a number of literature material, the other onlineexamination platform development with difficulties and take solutions. The design ideaof That paper is to use choose technical architecture, using J2EE platform technology,developed a performance optimization, extensibility, strong and safe and reliablealgorithm on-line examination system. That research method is based on the softwareengineering project management of the basic train of thought, through the systemdemand analysis and general design, detailed design, code go check, functional testing,and system integration process control to achieve design goal. That paper introduces thedesign of a key platform for to J2EE technology route, from the bottom of therequirement of points to realize the part function modules, including personnelmanagement, the test question management, information management, scores query,system configuration, system integration and eventually system test. That paper solvedesign difficulties of the online examination system is based on one of the randomtesting strategy and back of the intelligent algorithm, complete group rewindingfunction module; To solve the difficulties of another is through the UML modulecomplete teachers, students, administrators, the division of the three different roles and functions classification.That article through to the system management, examination paper group coildesign, the overall assessment papers and module of the deployment and management,realized one use of advanced technical architecture design and have reliable and sblankexam system of the online examination algorithm system architecture. In That system,system test sblank performance with independence, expansibility, easy portability andmany other features, greatly enhance the education level of network.
