database design help

Hello Guys,

**These are my requirements:**
1. Each Category has Multiple Groups
2. Each group has multiple Attributes
3. Each attribute has multiple values
So far i have come up with this DB Design
**CategoryGroups Table**
`GroupID` | `CatID[References Category(CatID)]` | `GroupName`

**CategoryAttributes Table**

`AttributeID` | `AttributeName` | `GroupID[References CategoryGroups(GroupID)]` | `AttributeValue`
So do you guys think this is a neat design?? Any suggestions??
