THE OBJECT CONSTRAINT LANGUAGE

"MDA promises a revolution in the way we develop software. This book is essential reading for anyone intending to adopt MDA technology." --Tony Clark, PhD
King's College, London

"Through examples, Jos and Anneke demonstrate the power and intuitiveness of OCL, and the key role that this language plays in implementing and promoting MDA. The theme, structure, contents, and, not lastly, the clarity of explanations recommend this book as the best advocate for learning, using, and promoting OCL, UML, and MDA. I am sure that this work will contribute in a significant manner to the development and widespread use of new software technologies." --Dan Chiorean
Head of the Computer Science Research Laboratory
Babes-Bolyai University, Cluj

"In this thoroughly revised edition, Jos and Anneke offer a concise, pragmatic, and pedagogic explanation of the Object Constraint Language (OCL) and its different applications. Their discussion of OCL's potential role in Model Driven Architecture (MDA) is timely and offers great insight into the way that UML can be taken to the next level of automated software development practice. I highly recommend this book to anyone who is looking to get the most out of UML.""

The release of Unified Modeling Language (UML) 2.0 places renewed emphasis on the Object Constraint Language (OCL). Within UML, OCL is the standard for specifying expressions that add vital information to object-oriented models and other object-modeling artifacts. Model Driven Architecture (MDA) relies on OCL to add the level ofprogramming detail necessary to enable platform-specific models (PSM) to communicate with platform-independent models (PIM).

This book is a practical, accessible guide to OCL for software architects, designers, and developers. Much care has been taken during the redesign of
