Description . 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. 1 Partial specification It is generally agreed that systems of a realistic size cannot be specified in single linear specifications, but rather should be decomposed into manageable chunks which can be specified separately. The traditional method for doing this is by hierarchical and functional decomposition. Nowadays, it is often claimed [11] that this is not the most natural or convenient (in relation to "perceived complexity") method -- rather systems s...
