Although each cell of the tuple represents a different thing (ie fact), they are all named by the same thing (ie string 'brown'). The string 'brown' is redundant. Because RM is a limited data model, it is hard to see this fact. It is more obvious in XDb1/TDM. Received on Tue Jul 06 2004 - 22:32:12 CDT
