一、系统要求
编写学生管理系统程序，应具备以下几点功能：
1.用户认证
系统用户分为学生、教师、管理员三个角色，系统可根据不同用户角色权限进入不同界面，所有用户角色需要通过身份验证才能登录系统进行操作。
2.学生登录
主要实现学生登录系统可查看本人基本信息、考试成绩、修改密码。
3.教师登录
主要实现教师登录系统可查看本人基本信息、学生信息、学生成绩、修改密码。
4.管理登录
主要实现管理员登录系统可查看本人基本信息、修改本人信息、查询老师信息、修改老师信息、录入老师信息、删除老师信息、查询学生信息、修改学生信息、录入学生信息、删除学生信息、查询考试成绩、修改考试成绩、录入考试成绩、删除考试成绩、修改登录密码。
5.退出系统
所以角色操作完成可退出系统登录。
二、用户信息
