内容摘要
随着科技的发展,科技应用越来越广泛。考试在线测试系统就是一个应用广泛的例子。但是,由于考试在线测试系统存在很多问题,例如,从后台数据库中抽取试题方面,由于算法的限制,使得生成试题速度受到影响。因此,本文以《数据结构》在线测试系统为实例进行研究,使得测试系统的性能得到进一步提高,具有现实意义。
本系统在研究了线测试系统背景和意义的基础上,基于vs2005和SQL2005数据库连接技术,设计实用的《数据结构》在线测试系统。系统设计实现时,以SQL2005数据库作为后台数据库,技术结合,实现了注册、查看和修改用户信息、找回登录密码、生成考试试卷、自动生成客观题分数及主观题答案自动存入数据库指定表中(以供教师评卷)的多项功能。重点是生成考试试卷、自动生成客观题分数及主观题答案自动存入数据库指定表中(以供教师评卷)。难点是对生成试题算法和怎样与后台教师评卷系统连接以快速生成考试分数(将主观题答案存入后台数据库制定表中)。
在解决难点时,对于快速生成试题算法主要是根据在数据库中的临时表中设置一个标志题型的字段去选题,这样比从数据库中的题型表中抽取试题速度快。对于客观题的评分机制是先统计答对题的数目,再去计算分数的方法进行设计。

Title:"Data Structure" On-line Testing System’s Design and Implementation
Abstract
With the development of technology, application of technology is more and more extensive. On-line testing system is a widely used example. However, in on-line testing system, there are many problems, such as building paper taken from the back-ending database, because of the limitation to algorithm, making the speed generating examination questions be affected. Therefore, to research the paper of "Data Structure" on-line testing system as an example in this area, making the performance on-line testing system has been further improved and of practical significance.
This system is studied on-line testing system in the study, based on the background and significance, using vs2005 and SQL2005 database connection method to design a practical "data structure" online testing system. The system with SQL2005 database as the back-ending database, with technologies in vs2005, achieve the registration well, view and modify user information, retrieve login password , generate examination papers, automatically generates scores of objective and sorer subjective questions answers automatically into specified the table of the database (for teachers marking) and other functions. Which focuses on generating test papers, automatically generates scores of objective and store subjective quest
