A crucial point is that this is only true if the system offers a mechanism to perform the decomposition. If it does not, then to the system itself your compound datatype is a single value.

This is the reason that nested relations is a valid approach within traditional RM - a compound datatype with a mechanism for its manipulation. Received on Fri Mar 03 2006 - 06:12:06 CST
