1.前言

😀请仔细看这段文字：为了帮助那些期末无法交作业的同学,开发了一个学生信息管理系统（垃圾版本，但是对初学者帮助大，强烈建议大家看我视频，而不是购买专栏）。

如果支持作者，也可以购买一份。你的支持是我创作的最大动力。

1.主界面

学生管理界面

用户管理界面

对话框界面

2.登录界面

界面设计因为PR用的不行事，所以用excel搞定

• 登陆界面
• 学生管理界面
• 管理员界面

6.【学生信息管理系统】需求分析

功能列表：
1.登陆界面，输入用户名和密码
2.权限管理，分为浏览权限和管理员权限,浏览权限无法删除和添加
3.学生添加、删除、搜索、导出、分页
4.学生信息：姓名、学号、年龄、年级、班级、微信、电话）

7.【学生信息管理系统】系统设计

• Sqlite3类:负责数据库操作
• MainWindow类：主界面
• Cell_Student类：学生管理界面
• Cell_Test类：测试界面
• Cell_Admin类：管理员界面
• Dlg_AddPerson类：添加用户界面
• Tester类：测试界面

8.【学生信息管理系统】详细设计

8.1数据库设计

• 学生表 student
  数据库字段名称类型id唯一标识主键自增name姓名Textage年龄integergrade年级integerclass班级integerstudentid学号integerphone电话TEXTwechat微信TEXT

  sql语句

CREATETABLE"student"("id"integerNOTNULLPRIMARYKEY AUTOINCREMENT,"name  "TEXT,"age "integer,"grade"integer,"class"integer,"studentid  "integer,"phone"TEXT,"wechat "TEXT);

• 用户表 user
  数据库字段名称类型username用户名TEXTpassword密码TEXTaut权限TEXT

  sql语句

CREATETABLE"username"("username"TEXT,"password"TEXT,"auth"TEXT);

8.2Sql语句设计

• 查询所有学生数量

selectcount(id)from student;

• 查询第几页学生数据

offset代表从第几条记录“之后“开始查询，limit表明查询多少条结果

select*from student orderby id limit2offset1;

• 增加学生

INSERTINTO"student"VALUES(NULL,'张三',12,3,2,1,15940224444,'asdzhang');

• 删除学生

deletefrom student where id =1;

• 清空学生表

deletefrom student

• 修改学生信息

update student set name ='asd'where id=25;

• 查询所有用户

select*from username

• 查询用户名是否存在

select*from username where username='admin';

• 修改用户权限

update username set auth='user';

• 添加单个用户

INSERTINTO"username"VALUES('admin',111,'admin');

• 删除单个用户

deletefrom username where username='admin';
