前言介绍
对于本教资考前指导系统的设计来说,系统开发主要是采用java语言技术,在整个系统的设计中应用MySQL数据库来完成数据存储,具体根据教资考前指导系统的现状来进行开发的,具体根据现实的需求来实现四六级在线考试系统网络化的管理,各类信息有序地进行存储,进入教资考前指导系统页面之后,方可开始操作主控界面,主要功能包括:
(1)前台:首页、教师问题、信息教资信息、复习资料、教学视频、在线练习、个人中心、后台管理
(2)管理员:首页、个人中心、学生管理、教师管理、学院名称管理、问题信息管理、教资信息管理、资料类型管理、复习资料管理、教学视频管理、资质面试管理、点评信息管理、系统管理。
(3)学生:首页、个人中心、问题信息管理、资质面试管理、点评信息管理
(4)教师:首页、个人中心、问题信息管理、资质面试管理、点评信息管理、练习题库管理、在线练习管理、练习管理
