"Software Engineering" presents a broad perspective on software systems engineering, concentrating on widely-used techniques for developing large-scale software systems. 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. The sixth edition has been restructured and updated, important new topics have been added and obsolete material has been cut. Reuse now focuses on component-based development and patterns; object-oriented design has a process focus and uses the UML; the chapters on requirements have been split to cover the requirements themselves and requirements engineering process; cost estimation has been updated to include the COCOMO 2 model.
