作业需求:
用户角色，讲师＼学员， 用户登陆后根据角色不同，能做的事情不同，分别如下
讲师视图
管理班级，可创建班级，根据学员qq号把学员加入班级
可创建指定班级的上课纪录，注意一节上课纪录对应多条学员的上课纪录， 即每节课都有整班学员上， 为了纪录每位学员的学习成绩，需在创建每节上课纪录是，同时 为这个班的每位学员创建一条上课纪录
为学员批改成绩， 一条一条的手动修改成绩
学员视图
提交作业
查看作业成绩
一个学员可以同时属于多个班级，就像报了Linux的同时也可以报名Python一样， 所以提交作业时需先选择班级，再选择具体上课的节数
附加：学员可以查看自己的班级成绩排名
数据库关联示意图：
思路解析：
按照数据库关联，操作班级教室分数和上课记录
讲师视图
1.管理班级，可创建班级
操作class表，输入classname后显示现在有几个课程几个课程表，然后让讲师创建TeacheCourse关联后才能创建班级
2. 根据学员qq号把学员加入班级
操作StudentTeachClass表，把qq号加入班级ID，然后显示，课程，课程表，班级，学员，
3. 可创建指定班级的上课纪录，注意一节上课纪录对应多条学员的上课纪录，即每节课都有整班学员上，为了纪录每位学员的学习成绩，需在创建每节上课纪录，同时为这个班的每位学员创建一条上课纪录
进入后显示班级，根据进入时候的班级讲师ID，操作teacherclass，操作teacher_course，找到对应的学生查看对应的班级的童鞋，操作RecordStudent
4. 为学员批改成绩， 一条一条的手动修改成绩
1. 进入后显示班级，根据进入时候的班级讲师ID，操作teacherclass，操作teacher_course，
2. 查看StudentHomework，查看学生的作业
3. 为学员一条一条修改成绩和创建上课记录，操作RecordScore
学员视图
1. 提交作业
显示课程，班级，上课节数，提交作业，做成绑定
2. 查看作业成绩
查看RecordScore
3. 一个学员可以同时属于多个班级，就像报了Linux的同时也可以报名Python一样， 所以提交作业时需先选择班级，再选择具体上课的节数
4. 附加：学员可以查看自己的班级成绩排名
操作recordscore
排名，读取出所有的成绩和姓名，然后进行排序
