功能实现：

第一步：数据库

1、表与关系

表1: 房间资源表（dbo.SYS_RoomResource）

Primary Key(主键):  RoomResourcesID

非主键ID值均是外键

表2: 楼栋信息表（dbo.SYS_FloorInformation）

Primary Key(主键):  FloorID

非主键ID值均是外键

（这里因为在这个表里边没有设置有默认值，所以没有默认值的那一列）

表3: 项目信息表（dbo.SYS_ProjectInformation）

Primary Key(主键):  ProjectID

非主键ID值均是外键

表4:  客户信息 （dbo.PW_ClientInformation）

Primary Key(主键):  ClientID

非主键ID值均是外键

表5:  预定表 （dbo.PW_ReserveUnit）

Primary Key(主键):  ReserveUnitID

非主键ID值均是外键

表6: 员工表 （dbo. SYS_Staff）

Primary Key(主键):  StaffID

非主键ID值均是外键

表7: 属性明细表（dbo.SYS_AttributeDetails）

Primary Key(主键):  AttributeDetailsID

3.换订预定信息

从界面上可以看到我们这里用到的控件有

功能实现：

第一步：数据库

1、表与关系

表1: 房间资源表（dbo.SYS_RoomResource）

Primary Key(主键):  RoomResourcesID

非主键ID值均是外键

表2: 楼栋信息表（dbo.SYS_FloorInformation）

Primary Key(主键):  FloorID

非主键ID值均是外键

（这里因为在这个表里边没有设置有默认值，所以没有默认值的那一列）

表3:  客户信息 （dbo.PW_ClientInformation）

Primary Key(主键):  ClientID

非主键ID值均是外键

表4:  预定表 （dbo.PW_ReserveUnit）

Primary Key(主键):  ReserveUnitID

非主键ID值均是外键

表5: 员工表 （dbo. SYS_Staff）

Primary Key(主键):  StaffID

非主键ID值均是外键
