Software Engineering presents a broad perspective on software systems engineering, concentrating on widely-used techniques for developing large-scale software systems. In seven parts, this best-selling book covers a wide spectrum of software processes from initial requirements elicitation through design and development to system evolution. It supports students taking undergraduate and graduate courses in software engineering and software engineers in industry who need to update their knowledge on new techniques such as requirements engineering, distributed systems architectures and system dependability.Extensive market research has ensured that this new edition is useful and relevant for both students and practising software engineers. The sixth edition has been restructured and updated, important new topics have been added and obsolete material has been cut. The end result is an even more focused book that is about 10% shorter than the previous edition.Changes from the fifth edition? There are new chapters covering software processes, distributed systems architectures, dependability and legacy systems.? Program examples are now in Java and graphical system models are described in
