I am looking for methods of generically storing hierarchies in a generalized
model. My main object type is 'Category'. 'Categories', if they had
differentiating attributes, would be sub typed as Brand, Brand Family, Retail
Groups, which themselves have relationships to other retail groups, whose
subtypes would be Regional Group, Divisional Group, etc. The ring relationships
is category to category, or if you refer to the subtypes specifically, Retail
Group to retail group.

Two separate categories are described below:

A:
1. Brand may be organized into Brand Family.
2. Brand may belong to more than 1 Brand Family.
3. Brand Family may have more than 1 Brand.
B:
1. National Chain may be comprised of many Regional Group.
2. Regional Group may be comprised of many Divisional Group.
3. Division Group may be comprised of sub-divisional Group.
4. etc.
5. National Chain, Regional Group, Divisional Group and Sub-divisional Group may
group Retail Establishment.
6. For one set of groups:
a) Retail Establishment may only exist once in all the groups.
b) group may not belong to more than 1 group (is a consolidation
hierarchy, representing sales rollup, for example)
7. For different set of groups
a) Retail Establishment may exist in many groups.
b) group may belong to many groups (my grouping, your grouping, we all
have a grouping).

Please explain a bit more and give some examples of what you mean by
"ring relationships" -- I've heard that phrase used in a variety of
ways.

Thanks.
