家庭物品管理系统(数据库课设)

1、沈阳理工大学课程设计专用纸 摘 要随着现代生活的发展，我国经济迅速发展，人民生活水平越来越好，家家户户都买了各种家电和生活用品，家庭物品也就越来越丰富了。但是，我们的家庭总是有限的，对于这些家庭物品我们需要有一个系统的整理。通过对数据库的学习，学习了一些对数据的整理，对此，为家庭物品做了一个管理系统。用Visual Basic 6.0作为前端开发工具，利用其提供的集成开发环境及支持面向对象的各种标准化的控件，尤其是对ADO的支持完成对数据库的各种操作。使这个系统能够添加、修改、删除家庭各成员与物品的信息相关信息，当进入到系统时，可以直接通过查询用户名或购买日期来浏览物品的信息，登陆到系统之后，

2、就可以对房间和物品信息进行添加、修改删除了，从而完成对家庭物品的整理，使各家庭成员更加方便地了解自己家里的物品信息关键字： 家庭物品 整理 方便0沈阳理工大学课程设计专用纸目 录1 系统功能概述32 数据库设计31.1 需求分析31.2 关系模型31.3 E-R模型41.4表结构设计53系统各功能模块的详细设计73.1主窗体73.2登录93.3查询113.4用户信息133.5物品信息183.6房间信息254参考文献28沈阳理工大学课程设计专用纸1 系统功能概述为该家庭物品管理系统设计一个MDI窗体作为主界面，在菜单栏创建了四个菜单：文件、查询、添加、用户名。（1） 文件中有两个子菜单：登录和退

3、出。这两个子菜单分别控制登录用户和退出整个程序。（2） 查询中有两个子菜单：按用户名查询和按日期查询。按用户名查询可以在用户输入某个用户名之后，显示该用户的物品情况；按日期查找可以在输入一个日期之后，显示该日期之后购买的所有物品。（3） 添加中有三个子菜单：添加用户、添加房间、添加物品。点击添加用户，可以对用户信息进行增删改查；点击添加房间，可以对房间信息进行增删改查操作；点击添加物品，则可以对物品信息进行增删改查操作。（4） 用户名按钮有一个子菜单：注销。用来注销已经成功登录的用户，如没有登录用户，该子菜单显示无用户，成功登录之后即显示已登录用户的名称。2 数据库设计1.1 需求分析 （1)

4、根据家庭成员的身份，为每个成员分配有一个专门的账号。 (2)此家庭物品系统管理能够添加、删除、修改、查询家庭成员的信息以及与房间、物品之间的联系。（3）在进入到家庭物品管理系统之后，不需要登陆就可以直接查询属于某个人的物品信息，也可以查询某个日期之后所购买的物品。（4）当用户成功登录时，菜单栏上能够显示该用户的名称，此时，用户才能对物品信息和家庭成员信息进行添加、修改、删除1.2 关系模型 （1）家庭成员信息表 Uuser：userName、password、sex、age、birthday、status、profession、hobby、wage （2）物品信息表 Item：itemDate
