摘要:系统从角色的角度可以分为三个模块,它们分别是考生模块,教师模块和管理员模块。考生模块主要功能包括考生登录、考生在线考试、考生修改本人密码、查看成绩和退出系统等。教师模块主要功能包括教师登录系统、教师查询学生成绩、教师管理试卷、教师管理试题、教师修改本人密码和退出系统等。管理员模块主要包含管理员登录、管理员管理考生信息、管理员管理班级信息、管理员修改本人密码、管理员管理教师信息和退出系统等。本系统投入使用后,学校需要考试时,试卷不用打印,减少财力的投入和纸张的使用;教师不用对试卷题目进行评分,大大减少了教师的工作量,具有较好的使用价值。

1 概述
本系统主要是面向在校学生和老师,还有一个用户是管理员。在此系统中,如果老师想要学生参加考试,首先得通知学生什么时候参加考试,并且老师需要在考生参加考试之前把相应的试卷和试题存储到数据库中的试卷表和题目表中。教师可以通过系统添加试卷和题目,系统中支持添加两种题型,两种题型分别为单项选择题、多项选择题,每道题分别是20分。考生可以在线考试。在考试界面上方有此次考试所规定的时间10分钟、计时时间和此次考试离交卷还剩余的时间。考生可以通过观察它们得到时间信息,这个计时时间是从0分钟开始向上计时,剩余时间从10分钟向下计时,当剩余时间变为0时,系统会自动交卷。……
