The Design And Implementation Of Online Examination System

As an important indicator of evaluation of teaching and learning, the examination is an integral part of educational modernization. The scientific and efficient mode of examination and the all-wave evaluation system of test results which have an important significance and role of improving the efficiency, enhancing the scientific and rational of the examination, promoting the course construction and reform, improving the quality of teaching. Based on these, according to the school characteristics and the actual situation of my college (Higher Vocational Technical College) school, we make full use of the network technology to develope the appropriate online examination system in our college, for realizing examination system of modern education. This article will described from the following aspects in detail, such as the developement tools of online examination system, the related technologies, the system requirements, the components and structures, the systems design scheme and the methods of the system implementation.The develpoement of this system is based on the JSP (Java Server Pages) dynamic web page technology,which adopts B/S structure (thin-client structure). The database adopts higher security SQL Server 2000, and Tomcat is selected as the System development server. The logical relations of online examination system are more complex. The system business logic and client-side display page are separated through the combine JSP with JavaBean to implement the complex management, which is of required by the application components. Early stage of system development, first of all, we analysis detaily and deeply to clear the users' needs, obtain the feasibility of conclusions of the system development and put forward the system logic model (from top to bottom) . Based of all, the system whole design is developed, sequentially, we confirm the system overall functional modules (Including system management module-information management of Papers, loose test management, examination management, information management, user management, candidates login module-online examination, loose testing, inquire results) . The required data objects and their access program and structure is analysed comprehensively, and the background database design is completed, also the safety design of the system is considered. Based on the overall design program, adopt the approach of bottom-up to achieve system function step by step. After testing, the system operates steadily.The system finally achieves the basic functions of each module. The database design (Papers structure, test questions structure) , the artificial random strategy papers, the test plan, enter the examination room, submit papers and automatic grades is the key of system; the design and realization of evaluation system analysis the results of examination objectively, however its effectiveness, and scientific rationality will be validated and consummated in the future useing of process.
