Research And Realization Of Computer Basic Course Examination System Based On B/S Mode

The way that non-paper examination based on computer technology substitutes for traditional manual examination has recently become an active research field. Computer basic course needs practical training, but the traditional examination method can only test students' logical reasoning ability and calculating ability, but can not exam the students' practical ability effectively. On the other hand, the non-paper examination method not only overcomes the disadvantage of the traditional test method, but also makes the test process more automatic and scientific.An on-line examination system based on network, database and ASP technology is proposed. The system has the feature of convenient utilization and simple operation, and it realizes the functions such as multi-users on-line examination, dynamic random paper generation, time control, automatic paper reading, paper subject inputting and modification, users management, courses management and score management etc, take the function of no-paper examination for example, it provide examination for every authorized student and gives the score timely.Firstly, the paper presents an automatic paper generation solution base on Population-Based Incremental Learning algorithm has the advantage of high speed and perfect stabilization. Under the condition with more constraints, the algorithm gets more adaptive, so it is an ideal algorithm for solving the problem of paper generation.Secondly, we study how to analyse the procedure information by using VBA tools, and to acquired document attributions which are essential for reading paper, We also realize the method of automatic reading office document subject.Finally, a file upload mechanism and method based on HTTP RFC1876 are researched. Compared with other file upload mechanisms, our machanism has more advantages in the aspects of authentication management, security, flexibility etc.
