学生网上练习自测系统设计 摘要 随着计算机技术的发展及计算机的日益普及，知识更替日新月异的时代，网络化考试已成为大势所趋。网络化考试也越来越成为各种考试的好帮手，在电子政务蓬勃发展的时候，职称考试等考试的网络化就显得尤其的重要了。 本文首先进行系统的需求分析，得出要建的各个系统模块。其次用Microsoft ODBC数据源管理支持下的数据库Microsoft Access建立系统运行所要的后台数据库。本考试系统具有自动出题、随机出题、自动阅卷计分、在线记时考试、用户帐户管理、批量添加考生、成绩存档等功能，它将有效的提高考试效率。信息查询eing long with the development of the computer technology, knowledge of the times change with each passing day, information technology is that development of enterprises has provided opportunities as well as a challenge. the development of the exam online system is so fast that it will become a good helper of the multiplicity exam. Especial in the quick development of the nationals information construction, the exam-system will play a important role in the construction. First of all, it is necessarily to analyze the requirement of this system in order to constitute the module needed. Secondly, we must to create the Database of the system which supported by the Microsoft ODBC Data source. So that this system have several important functions, such as set question automation, set question randomly, count Statistic the score automatically, online test by time keeping, the management of user account etc, it improves examination efficiency with high efficient. In the designing of this system, personnel files, staff information input, modify, delete, query, print and associated personnel authority settings, and so on, the angle from the software engineering has been have carried out science but rigorous expound. we try our best to make the program to achieve strongly transplantation to ensure it will have a certain application foreground.
