Abstract
A universal relation view is a view
(external schema) on top of a relational
database schema (conceptual schema). It
shows the whole database as a single
fictitious universal relation. It
provides a user-friendly interface where
queries can be expressed without
navigation, even on the level of
relations, as far as possible. We
carefully develop the fundamental
decisions of our approach: different
kinds of users should have a consistent
understanding of the view; the
underlying database schema should
satisfy a new desirable property called
unambiguity. Besides unambiguity and the
so-called universal scheme assumption
our approach does not rely on any
further prerequisites.
