Abstract
Manifestations of the "universal relation assumption" can be
seen either as definitions of a one-relation user
view of data, or as algorithms for answering queries about
arbitrary sets of attributes. In this paper we
explore equivalences between these two points of view.
We show that if the user's view is the representative
instance, then our ablility to answer queries about the
universal relation, by applying relational algebra to
the actual database, is equivalent to a "boundedness" condition
on the dependencies of the database scheme.
Further, whenever this condition holds, there is a finite union
of lossless tableau mappings that produces the desired relation.
