需求:
设计一款教务管理系统,实现如下功能:
1、此教务管理系统面向三种身份，学生、教职工、系统管理员
2、要有登录界面，在登录界面能根据不同身份自动选择登录入口
3、教职工凭借工号和密码登录,学生凭借学号和密码登录,系统管理员设置特定帐号和密码
4、教职工
（1）教职工基本属性：姓名 性别 出生日期 职称 工资 工号 登录密码
（2）教职工的功能：修改个人信息、查看个人信息、浏览高级/低级消息、申请发布低级消息、管理自己发布的低级消息
5、学生
（1）学生的基本属性：姓名 性别 出生日期 学院 班主任 专业 学号 登录密码 级段
（2）学生的功能：修改个人信息、查看个人信息、浏览二级消息
6、系统管理员
（1）系统管理员的基本属性：帐号 登录密码
（2）系统管理员的功能：注册教职工、注册学生、管理所有教职工\学生信息、发布高级级消息、管理所有消息、审核低级消息发布申请，初始化教职工和学生密码
简单设计：
1、在MySQL数据库中创建数据库：test
2、创建表：LoginAccount StudentInfo TeacherInfo AllMessage DefaultPassword PositionList
3、LoginAccount：Id Account Password AccountLevel
Id是账户序号
Account对于系统管理员是帐号，对于教职工是工号，对于学生是学号
Password密码
AccountLevel账户级别 0系统管理员 1教职工 2学生
4、StudentInfo: Id Name Gender Birth Academy TeacherNo Major StudentNo(长度固定为12) EntryDate
TeacherId: 班主任的工号
EntryDate：入学时间
5、TeacherInfo：Id Name Gender Birth PositionNo Salary TeacherNo(长度固定为5) EntryDate
PositionNo: 职务编号
EntryDate: 入职时间
6、AllMessage：Id MsgLevel SenderNo SenderName SendTime Title Content Statu
Statu消息状态 wait等待审核 pass审核通过 fail审核未通过
MsgLevel 0高级消息 1低级消息
7、登录界面：
（1）登录入口设置为三个：管理员入口 教职工入口 学生入口
（2）在登录时，检验密码和账户是否匹配，然后再检验账户级别和所选登录入口是否匹配，都匹配则登录成功，反之，登录失败
8、学生界面：
（1）设置功能菜单：个人信息<查看，修改> 消息
9、教职工界面：
（1）设置功能菜单：个人信息<查看，修改> 消息<消息列表，发布消息，我的消息<删除> >
10、管理员界面：
（1）设置功能菜单：教职工<浏览，注册，修改，删除，初始化密码> 学生<浏览，注册，修改，删除，初始化密码> 消息<消息列表，发布消息，审核消息，删除消息>
11、DefaultPassword：Id AccountLevel Password
各个级别的初始化密码
12、PositionList：Id PositionNo PositionName
职务列表，PositionNo职务编号 PositionName职务名称
在Scripts文件目录下打开cmd，输入命令 pip install mysqlclient 连接数据库，数据库连接完成以后打开mysql，source+空格+导入的数据库（用鼠标拖入），导入数据库，show databases->use+导入的数据库名->show tables from 导入的数据库名->select * from 数据库中的表名 查询完成后就可以在Python中运行主函数，进行教务系统管理了
类设计：
主函数
