The Design And Implementation Of Online Examination System Based On Ajax

Development and application of computer technology to people’s lives and work brought great convenience, more and more are beginning to use computer technology to manage all aspects of the work, in order to achieve higher efficiency. Online examination system as the online exam, too, because the growing number of test types and test the expanded scale, the traditional manual management mode was exposed various shortcomings, such as manual handling large amounts of data need to spend a lot of labor and the efficiency is very low, prone to error, poor maintenance. These shortcomings of the traditional management model that the use of computer technology to manage the need for the examination. Therefore, this article on the theme of an online examination system, system development aims to address the online exam in the information technology aspects of the problems faced.In this thesis after a demand for research and analysis on the basis of online examination system design and implementation. Design include:(1) design and development of the bank management modules:implementation of new kinds of questions to add, add, modify and delete topics, and subject to export;(2) design and development of the exam test paper modules:to achieve a selection of papers generated paper is the subject of type, select papers of degree of difficulty, the proportion of selected questions scores, papers, and approval of papers generated functions;(3) design and development of test management module:implementation of test time setting, the setting of the exam staff, issued a notice examinations, examination arrangements query to generate examination papers, examination scripts and to submit test scores generated functions;(4) design and development of candidate management module: implementation of candidates information to add, change information on the candidates, the candidate information and analysis of candidates’ knowledge of inquiry points to master functions;(5) design and development of performance management modules: implementation of the entry test scores for examinees to modify, for test scores for the deletion, the query performance of the candidates, candidates’ examination results and statistical functions;(6) design and development of system maintenance function modules:implementation of the system’s user management, data maintenance and system logs to maintain function.The system design and development using Ajax technology, the development platform used Visual Studio2008, the database server using a SQL Server2005, Asp.net application framework is the use of three-tier architecture. Currently, the online examination management system has been formally launched in the unit running, running well and has really improved staff productivity and accuracy for the examination of information technology to make a contribution.
