The art, craft, discipline, logic, practice, and science of developing large-scale software products needs a believable, professional base. The textbooks in this three-volume set combine informal, engineeringly sound practice with the rigour of formal, mathematics-based approaches.

Volume 1 covers the basic principles and techniques of formal methods abstraction and modelling. First this book provides a sound, but simple basis of insight into discrete mathematics: numbers, sets, Cartesians, types, functions, the Lambda Calculus, algebras, and mathematical logic. Then it trains its readers in basic property- and model-oriented specification principles and techniques. The model-oriented concepts that are common to such specification languages as B, VDM-SL, and Z are explained here using the RAISE specification language (RSL). This book then covers the basic principles of applicative (functional), imperative, and concurrent (parallel) specification programming. Finally, the volume contains a comprehensive glossary of software engineering, and extensive indexes and references.

These volumes are suitable for self-study by practicing software engineers and for use in university undergraduate and graduate courses on software engineering. Lecturers will be supported with a comprehensive guide to designing modules based on the textbooks, with solutions to many of the exercises presented, and with a complete set of lecture slides.

Respect to (wrt) formal techniques. If they do, as some indeed do, bring material on so-called "Formal Methods", then that material is typically "tucked away" in a separate chapter (so named). In our mind, the interplay between informal and formal techniques, that is, between informal descriptions and formal specifications, informal reasoning and formal verification, and so on, permeates all of software engineering. The potential of (using) formal techniques shapes all phases, stages and steps of.

Are treated by the software engineer. The techniques of presenting highlighted characterisations, definitions, principles, techniques and tools are basically those used for descriptive texts. • Tools. Tools are here seen as intellectual (or even software) devices that aid in accomplishing a task, that is, are used in performing an operation or necessary in the practice of the profession of software engineering. The tool for presenting highlighted characterisations, definitions, principles,.

Of mathematics. Mathematics is the science of abstraction. So what is the semantics of RSL specifications? To appreciate and understand the choice made for the semantics of RSL, let us consider some very basic RSL specifications. Usually a specification names "things". Example 1.7 Semantics of Class Specifications: Our example is just that: It does not model anything "practical", but illustrates, at a minimum cost of symbols, what we wish to say about semantics. [0] scheme EXAMPLE = [ 1] class.

Incorporating the A-calculus, as a notation, in the main specification language of these volumes, RSL. As part of that, we introduce the indispensable language construct let ... in ... end, explained in terms of A-function application. 2 We end with an introduction of the notion of recursively defined functions, fix points, a fix point operator and fix point evaluation of function application. 7.1 Informal Introduction In the A-calculus everything is functions. To express such A-calculus.

Search in graph, as operations. 5. Patient Medical Record Algebra: The patient medical record algebra has, as carrier, all conceivable patient medical records, each consisting of one dossier. Each dossier consists of one or more sheets (i.e., records) that are of the following kinds: prior medical history, interview records, analysis records, diagnostics determination, treatment plans (including prescriptions), observations of effects of treatment, etc. In addition the carrier also includes these.
