That does Nigel thanx. In the DB I am trying to design I can see
lots of 1:M relationships but I can't see a case for using a join

1:M doesn't need an additional table - M:M does.
Sometimes the link table may be disguised because its a useful entity
in its own right... ie it contains additional info with the
relationship.
