Formal Methods Fact File: VDM and Z (Wiley Series in Software Engineering Practice)

Formal Methods Fact File VDM and Z Andrew Harry Formal methods provide a means of specifying computer systems that is unambiguous,concise and well suited to the development of complex software systems for which accuracy and reliability are critical. Heavily mathematical and seemingly difficult to learn, for many they hold little appeal. Andrew Harry speaks as a programmer who has travelled the difficult route to an understanding of formal methods techniques, and knows why it's worth the effort. He explains, in refreshingly simple terms, what formal methods are, why we need them, what should motivate our choice of methods and how to use them effectively. The book presents a novel view of formal methods, spanning the range of specification techniques. An overview of the different styles of formal notation is followed by detailed chapters on the two most popular languages, VDM and Z, consistent with the latest draft standards. There is a readable account of the underlying maths, a short introduction to semantics for proof, and a survey of tools available. Teaching aids include quick reference appendices on the notation and syntax of VDM and Z; exercises (and their solutions); and a useful glossary of terms. A more populist account than most, this book's 'informal' treatment of the subject will appeal to students and industrial programmers who want to know more but find little on the shelves for the novice.
