数据库课程设计（学生宿舍管理系统）附sql文件、源代码和Word模板
对于寝室长而言，系统中需要提供，寝室人员信息显示、报修功能、报修状态查看、修改密码的功能。（3）管理员管理：查看学生住宿信息（按学号搜索、空白搜索全部）、管理学生住宿信息（添加学生住宿信息、删除学生住宿信息）、处理保修信息（修改处理状况）、管理学生账号（添加和删除）、修改密码。管理学生住宿信息：添加需要对学生采集学号、姓名、性别、专业、班级、宿舍号、寝楼、联系电话，删除学生信息只需要提供学生的学号

目录
一、功能要求
1、设计内容
设计一个学生宿舍管理系统，该系统的用户由寝室长和宿管员组成，不同的用户拥有不同的管理权限，各自完成各自的管理功能，首先是登录，登录的时候首先要判断用户的身份，合法的用户然后进入到系统主界面中，不同的用户看到不同的系统功能。
2、学生宿舍管理系统主要功能
（1）登录界面
（2）寝室长界面：寝室人员信息、保修操作、修改密码。
（3）管理员管理：查看学生住宿信息（按学号搜索、空白搜索全部）、管理学生住宿信息（添加学生住宿信息、删除学生住宿信息）、处理保修信息（修改处理状况）、管理学生账号（添加和删除）、修改密码。
3、学生宿舍管理系统数据库表单（可以按照需求增、删、改）
（1）寝室长信息表单：账号、密码
（2）宿管员信息表单：账号、密码
（3）报修信息表单：报修编号、寝楼、宿舍号、时间、问题、状况
（4）学生信息表单：学号、姓名、性别、专业、班级、宿舍号、寝楼、联系电话
二、系统需求分析
2.1 功能需求分析
首先，基本功能是登录。登录有两种身份：寝室长或宿管员。对于寝室长而言，系统中需要提供，寝室人员信息显示、报修功能、报修状态查看、修改密码的功能。对于管理员而言，系统需要提供查看学生住宿信息，管理学生住宿信息，处理报修，管理学生账号，修改密码的功能
图1.1 系统功能模块图
2.2数据需求分析
寝室长登录需要对寝室长采集账号和密码；
寝室人员信息显示：在界面上显示寝室人员的全部信息，由宿管员界面添加学生信息采集；
报修操作需要对寝室长采集寝楼、宿舍号、时间、问题的信息；
修改密码需要采集原密码和新密码；
宿管员登录需要对宿管员采集用户名和用户密码；
查看学生住宿信息:开始显示全部学生的信息，通过搜索按钮需要输入对应的学号（模糊匹配）、输入空白则搜索全部学生信息；
管理学生住宿信息：添加需要对学生采集学号、姓名、性别、专业、班级、宿舍号、寝楼、联系电话，删除学生信息只需要提供学生的学号；
处理报修：需要采集处理序号，选择处理的状况；
管理学生账号：需要采集学生的账号和密码后可以选择删除还是添加；
修改密码需要采集原密码和新密码；
2.3 业务规则及完整性约束分析
寝室长（账号、密码）
学生（学号、姓名、性别、专业、班级、宿舍号、寝楼、联系电话）
报修信息（报修编号、寝楼（外码）、宿舍号、时间、问题、状况）
宿管员（账号、密码）
三、数据库概念结构设计
3.1 局部E-R图
图2.1寝室长实体E-R图
图2.2顾客实体E-R图
图2.3订单实体E-R图
图2.4菜单实体E-R图
四、 数据库物理结构设计
4.1创建数据库：
CREATE database susheSystem;4.2创建Suguan表：
use susheSystem;
create table Suguan(
Zhanghao CHAR(10) PRIMARY KEY,
Mima CHAR(20) NOT null
);4.3创建qinshizhang表：
create table qinshizhang(
Zhanghao1 CHAR(10) PRIMARY KEY,
Mima1 CHAR(20) NOT null
);4.4创建student表：
CREATE Table student(
Xuehao CHAR(20) PRIMARY KEY, #学号
Name CHAR(10) NOT NULL, #姓名
Sex CHAR(5) NOT NULL, #性别
Specialistion CHAR(10) NOT NULL,#专业
Class CHAR(10) NOT NULL,#班级
Dormitory CHAR(10) NOT NULL,#宿舍号
Qinlou CHAR(10) NOT NULL,#寝楼
Phone CHAR(20)#电话
);4.5创建baoxun表：
CREATE TABLE baoxun(
Number1 int(2) NOT NULL AUTO_INCREMENT,#报修编号
Qinlou CHAR(10) NOT NULL,#寝楼
Dormitory CHAR(10) NOT NULL,#宿舍号
Time1 DATE ,#时间
Question char(100) NOT NULL,#问题
Situation char(10) DEFAULT '等待处理',#状况
PRIMARY KEY (Number1) USING BTREE,
FOREIGN KEY (Qinlou) REFERENCES Suguan(zhanghao)
);4.6创建存储过程my
delimiter $
create procedure my()
begin
alter table baoxun drop Number1;
alter table baoxun add Number1 int(2) not null auto_increment primary key first;
end $
delimiter ;
设置定时事件
show variables like '%event_sche%';-- 查看事件计划是否开启
set global event_scheduler=1;
create event on1 on schedule every 1 second do call my();-- 创建定时事务4.7另一种实现利用触发器实现当前时间
/*delimiter $
create procedure my(in id int)
begin
declare ti date default 0;
set ti=curdate();
update baoxun set Time1=ti where Number1=id;
end $
delimiter ;
delimiter $
create trigger my1 after insert on baoxun for each row
begin
call my(new.Number1);
end $
delimiter ;
drop trigger if exists my;
delimiter $
create trigger my2 after insert on baoxun for each row
begin
declare ti date default 0;
set ti=curdate();
update baoxun set Time1=ti where Number1=new.Number1;
end $
delimiter ;
INSERT INTO baoxun(Qinlou,Dormitory,Question) VALUES ('紫园一栋', '107','门坏了');
