数据库结课作业——校园失物招领系统
作者：互联网
目录
杂七杂八
起因
因为数据库实验结课作业要结合理论课和具体实现来完成，而老师给的题目中，只有这个很简单且没多少人选，再加上有现成的案例来“供我们借鉴”——支付宝完美校园中的失物招领系统，所以有了这么个粗制滥造。
项目环境
pycharm +sql server
python简单，加上sql server的可视化界面十分友好，所以选择这两位搭配。
前端界面的选择
由于pyqt5的简单易上手，且同时有qt designer的可视化，pyqt5当之无愧。
数据库理论阶段
数据库模型
易得三个实体——用户、管理员、物品，再结合现实失物招领的特点，我们赋予相关实体联系以及各自的属性，其中有特点的是信誉等级这个属性。具体的sql语句如下：
CREATE TABLE 用户
(
账号 nvarchar(10) PRIMARY KEY,
姓名 nvarchar(10) NOT NULL,
密码 nvarchar(20) NOT NULL DEFAULT '123456',
网络匿称 nvarchar(20) NOT NULL DEFAULT '神秘用户',
联系方式 nvarchar(20) NOT NULL UNIQUE,
二次密码 nvarchar(10),
信誉等级 nvarchar(10) DEFAULT '0',
认领成功数 nvarchar(10) DEFAULT '0'
)
CREATE TABLE 物品
(
物品id nvarchar(20) PRIMARY KEY ,
档案号 int identity(1,1) ,
案件性质 nvarchar(4) CHECK (案件性质 IN('失物','招领')),
种类 nvarchar(10) CHECK (种类 IN('书籍/文具','证件','雨伞/钥匙','电子产品','其他')),
时间 date DEFAULT (GETDATE()) ,
区域 nvarchar(10) CHECK (区域 IN('A区','B区','C区','D区','其他')),
相关描述 nvarchar(40) DEFAULT '用户暂未添加相关描述',
物品状态 nvarchar(10) CHECK (物品状态 IN('处理中','已找回','无人认领'))
)
CREATE TABLE 管理员
(
账号 nvarchar(10) PRIMARY KEY,
密码 nvarchar(20) NOT NULL DEFAULT '123456789',
区域 nvarchar(10) CHECK (区域 IN('A区','B区','C区','D区','其他')),
二次密码 nvarchar(10)
)
CREATE TABLE 认领关系
(
物品id nvarchar(20) FOREIGN KEY REFERENCES 物品(物品id),
发布人账号 nvarchar(10) FOREIGN KEY REFERENCES 用户(账号),
认领人账号 nvarchar(10) FOREIGN KEY REFERENCES 用户(账号)
)
代码实现
相关功能
我们仨讨论我们的系统应该有哪些功能时，确实粗现了一些分歧，主要是我想要的功能太多——插入图片、信誉等级（荣誉系统）、物品状态的实时更新，舍去这些功能后，我们最开始的版本的功能如下：
- 用户/管理员登录
- 用户注册
- 用户找回密码
- 用户发布失物/招领
- 用户修改自己的网络昵称/密码
- 用户删除自己的发布
- 用户筛选物品
- 管理员删除用户发布
- 管理员筛选物品
- 管理员筛选用户
- 管理员修改物品的相关信息
- 管理员修改用户的密码
- 管理员获得年度的统计信息（折线图、饼状图、柱状图）
- 管理员导出物品/用户信息（excel）
具体的实现代码会在最后。最终的代码我自己还是修改了一下，加入了我自己想要的几个功能（图片我懒得弄了哈哈）。
UI设计
pyqt5的逻辑很简单，按钮与槽函数(功能函数)的关联，我们在ui文件上摆摆样子，能实现最简单的逻辑交互就好。
