摘要
论述了《计算机操作系统》试题库系统的总体设计结构,系统采用B/S结构,应用ASP技术和采用Access数据库来构成试题库系统,使用ODBC技术连接后台数据库,并且给出了本系统的需求分析、系统结构图、系统各模块的功能,在数据库设计中用数据流图来表达数据和处理的关系,说明了每个数据库表的详细信息。系统在抽题算法上,采用了随机抽取与设置难度系数相结合的方式,这样可以使每个学生抽到的试题与其他学生不完全一样,并且试卷中各种难度试题数量的分布更加合理化、科学化,同时给出了详细的抽取算法。
This article discusses the "computer operating system"questions the overall design of the system, the system uses the B/S structure, and uses the Access database system using the ASP technology to constitute tries the question bank system, uses the ODBC technology connection backstage database, and has given the system structure drawing, system various modules function, in database each table detailed information. This system in pulls out in the topic algorithm, has selected the method which the draw an item at random and the establishment difficulty coefficient unifies, like this each student pulls out the test question is not completely same as other students, and in examination paper each kind of difficulty test question quantity distribution even more rationalize, scientific style, simultaneously has given the detailed extraction algorithm.
