## 一、项目简介 ##

毕业论文答辩系统利用网络沟通、计算机信息存储管理，有着与传统的方式所无法替代的优点。比如计算检索速度特别快、可靠性特别高、存储容量特别大、保密性特别好、可保存时间特别长、成本特别低等。在工作效率上，能够得到极大地提高，延伸至服务水平也会有好的收获，有了网络，毕业论文答辩系统的各方面的管理更加科学和系统，更加规范和简便。

## 二、系统功能 ##

本毕业论文答辩系统主要包括三大功能模块，即管理员模块、教师模块和学生模块。

（1）管理员模块：主要功能有：首页、个人中心、学生管理、教师管理、课题信息管理、选题信息管理、论文信息管理、论文评分管理、答辩通知管理、成绩评定管理、系统管理。

（2）教师用户：首页、个人中心、课题信息管理、选题信息管理、论文信息管理、论文评分管理、答辩通知管理、成绩评定管理。

（3）学生：首页、个人中心、选题信息管理、论文信息管理、论文评分管理、成绩评定管理。
