(Thinking this through)
Ok, so that's a one-to-many relationship. Ummm, I'm trying to think
of a good example... one person, many email addresses. If the person
goes away, their email addresses should, but not vice-versa. Right.
And a many-to-many relationship would have to be modeled with a link
table, so that's not a problem.
I think that'll work.
