Please show that "brown" is a value in RM without context to tuple and attribute.

Also see C.J. Dates "Intro to Db Sys", 6th Ed, Chapter 19, Section 5, p560 Further Topics / Relation-Valued Attributes, where he discusses the concept of values being a relation: "as we explained that such 'scalars' can have a structure of arbitrary complexity when viewed at a lower level of abstraction and we mentioned that they might even be relations. In other words, we can have domains, and therefore attributes, that are relation-valued, and thus have relations that contain other relations inside themseleves and so on recursively to any levels. Not only does this concept appear in TM also, it has been implemented. Received on Tue Jul 20 2004 - 19:51:53 CDT
