Alfredo,
I thought in most SQL DBMSses all SQL (result) sets are in fact (casted to) arrays, since they can contain duplicates and have an (implicit) ordering even if you do not user order by (ROW_NUMBER/ROWID anyone?), this is a SQL/DBMS issue BTW and not a general RM one. In a sense this is understandable because it prevents constantly casting between sets and arrays.
Mailing internationally is often a must, but that does not make it any
easier!
Having a generalized international address (entity) that is just
globally constrained is a real PITA, because this usually means
one-size-does-not-fit-anybody. Maybe using "dynamic" contstraints
(based on country) would be a more interesting option.
