Description
Book SynopsisA practical approach to enhancing quality in software models using UML Version 2.0
Despite its increasing usage, many companies are not taking the best advantage of UML and, occasionally, individuals have experienced frustration in applying its standards. Perhaps this is because they have not yet read this book!
-From the Foreword by Prof. Brian Henderson-Sellers
This book presents a practical checklist approach to enhancing the quality of software models created with the Unified Modeling Language (UML) Version 2.0. The foundation for quality is set by the discussion on the nature and creation of UML models. This is followed by a demonstration of how to apply verification and validation checks to these models with three foci: syntactical correctness, semantic meaningfulness, and aesthetic symmetry. The quality work is carried out within three distinct yet related modeling spaces:
* Model of problem space (MOPS)
* Model of solution space (MOSS
Trade Review"...is just the book to help one use the UML effectively...I highly recommend this book." (
Software Quality Professional, December 2006)
"I recommend this book to all those…using UML in small or medium-sized projects…it will serve as a useful guide for their next UML modeling task." (Computing Reviews.com, November 3, 2005)
