我认为比较通用的权限设计
某网权限系统设计 ,自自己认为还可以...哈哈.
作者:小男
一．要求：
1.
用户分组
...
组里有这些权限
...
单个用户也能设置权限
..
2.
时间段权限
..
就是某个时间段某个组或某个人是什么权限
..
3.
权限列表
.

二．实现：
注
:
示例假设当前时间为
2007-2-1
[Sys_Member_ Popedom _Group]
Group_Id Group_Name Group_Description
100
普通用户
200 VIP
用户
300
认证用户
1000
常用限制
(
惩罚
)
限制发供求，限制访问论坛等
2000
限制发供应信息
3000
限制发求购信息
4000
变态限制组
5000
再变态限制组
20000
无权限用户
.........
此表为“用户权限组”。
Group_Id
非自动编号，
Group_Id
越大权重越大
(
用户同时属于多组时以当前最大
Group_Id
为准
)
[Sys_Member_Popedom_List]
Popedom_Id Popedom_Flag Popedom_Description
1 Info_Add_Sell
增加供应信息
(
是
/
否
)
2 Info_Add_Buy
增加求购信息
(
是
/
否
)
3 Info_Add_DayCount
用户每天能增加多少供求信息
.............
此表为每个“权限名定义”表。
[Member_Popedom_List]
Member_Id Group_Id Time_Start Time_End
61 100 20061202 99999999 (

"
常用限制
")
........
此表为“用户时间段权限组”表。即某个时间段里，某个用户属于哪些用户组。
[Member_Popedom_Group]
(
详细记录每个用户组的权限
)
Group_Id Popedom_Flag Popedom_Value(int)
100 Info_Add_Sell 1
100 Info_Add_Buy 1
100 Info_Add_DayCount 10
1000 Info_Add_DayCount 0
........
1
．每个“允许”操作的权限必须明确定义。存入此表
.
2
．此表
Group_Id
与用户组表
[Sys_Member_Group]
的
Group_Id
对应
Popedom_Flag
与
[Sys_Member_Popedom]
的
Popedom_Flag
对应
.Popedom_Value
字段存入相应权限的逻辑或数值。
3
．权限值
Popedom_Value
为
int
类型，保存某个权限（是
/
否）或数字值。“允许”为
1,
“拒绝”为
0
4
．用户多个组的权限
Popedom_Value
以最小值为准，
例：先运行附录里建表语句，查询用户
id=61
的当前权限“
Info_Add_DayCount
”的值
Select
IsNull
(
Min
(value),
0
)
From
(
Select
TOP
1
Member_Popedom_Group.Popedom_Value value
FROM Member_Popedom_List INNER JOIN
Member_Popedom_Group ON
Member_Popedom_List.Group_Id = Member_Popedom_Group.Group_Id
Where (Member_Popedom_Group.Popedom_Flag = ' Info_Add_DayCount ' ) AND
(Member_Popedom_List.Member_Id = 61 ) AND
(Member_Popedom_List.Time_End >= 20070302 )
ORDER BY Member_Popedom_List.Group_Id DESC ) a
FROM Member_Popedom_List INNER JOIN
Member_Popedom_Group ON
Member_Popedom_List.Group_Id = Member_Popedom_Group.Group_Id
Where (Member_Popedom_Group.Popedom_Flag = ' Info_Add_DayCount ' ) AND
(Member_Popedom_List.Member_Id = 61 ) AND
(Member_Popedom_List.Time_End >= 20070302 )
ORDER BY Member_Popedom_List.Group_Id DESC ) a
结果为
0
如日期至
20070303
（把红色字改成
20070303
）
结果为
10
即惩罚结束。
