The Design And Implementation Of Online Examination System In Higher Vocational Colleges

Carried out in teaching vocational colleges, in order to better assess the effect of different students, at the end of the course of study usually need to develop appropriate evaluation examination program for students, but in the traditional paper-based examinations carried out at, due to excessive human intervention, so it makes the test results prone to errors. In addition, since all examination papers and the results are used to store text, but also easily lost or damaged, is not conducive to the school calendar year performance analysis and prediction, and generation and application of information technology can be a good solution to this problem, so the design based on the new exam pattern information technology will become a trend.In this paper, the realization, the system analyzes the research background, research status and the main work of this paper, and then from the management information systems, database technologies, UML modeling technology and B / S architecture, such as the perspective of the system to achieve key technical theory, and use the UML from the test subjects management, paper formulate management use case diagrams, user paper management, test category management, test management, department of information management and systems management point of view of the system functional requirements, environmental requirements, performance requirements, and security requirements, etc. point of view of non-functional requirements of the system, after a clear system requirements, technical framework papers from the system design, physical topology architecture design and functional point of view of the overall design of the system design process, and the use of UML package diagram and class diagram of the system function module detailed design analysis, in addition, in order to ensure the efficiency and security of the system data access, database design, and system security from two different angles were designed to design analysis, the final analysis and online examination system based on the needs of vocational colleges design results, using the Java programming language, Myeclipse development platform, apache tomcat server and MySQL database to achieve a system function, and use Jmeterand Badboy testing tools such as the system was tested.Design and implementation of online examination system of vocational colleges, changed the traditional paper-based exam pattern colleges, making the curriculum teachers can devote more energy to design exams, rather than complicated examination affairs not only reduces the workload of the course teacher exams, but also can use computers to automatically calculate, low error rate and long-term storage features for testing services, not only to improve the efficiency and quality of test administration, but also for the statistical analysis of student achievement and projections provide good support.
