MW: OK until the last bit. You seem to be equating relationships to
relations. Not a good move in my view. I take a relationship to be a real
world phenomenon and a relation to be a mathematical structure. Whilst
relations can be used to represent relationships, there is certainly not
necessarily a one-to-one relationship between relationships and relations.
For example in relational databases it is common practice to use a single
relation (record type) to represent multiple real world relationships.    (03)
