Research in software engineering proceeds in two almost unrelated streams: the formal stream is an offspring of mathematical logic and relies completely on the usage of symbolic language; the pragmatik stream in derived from decades of practical development of large systems and applies informal (or only weakly formal notations, like diagrams, tables and natural languages.
In this book, Hussmann builds a bridge between the pragmatic methods for the design of information systems and the formal, mathematical background. Firstly, the principal feasibilty of an integraton of the different methods is demonstrated, secondly, the formalism is used as a systematic semantic analysis of the concepts in SSADM, a British standard structured software engineering method. Third, a way is shown to obtain a hybrid formalpragmatic specification using a combination of SSADM notations and formal (SPECTRUM) specifications.

This well written look encourages scientists and software engineers to apply formal methods to practical software development problems.
