Abstract

This paper discusses theoretical background for the use of Z as a language for partial specification, in particular techniques for checking consistency between viewpoint specifications. The main technique used is unification, i.e. finding a (candidate) least common refinement. The corresponding notion of consistency between specifications turns out to be different from the known notions of consistency for single Z specifications. A key role is played by correspondence relations between the data types used in the various viewpoints.
