Question

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??

Answer 1

Apart from naming your second table GroupAttributes, because it doesn’t know anything about Category, this is one, most used, good approach. You have multiple 1:N (one to many) relationships, and you’re referencing tables in the right way.
