Acknowledgments

A book like this is always a joint effort, but not only of the direct contributors, such as the editorial staff of Addison-Wesley (and I'd especially like to thank my editorial helpers Kathy Glidden and Carol Noble) but of many others who in their own way have raised the bar for all of us. The core team members working on the UML Cris Kobryn, Eran Gery, Jim Rumbaugh, Bran Selic and many many others are certainly among those that should be acknowledged in bringing forth a useful standard language for capturing and manipulating models of systems. Thanks to David Harel, inventor of Statecharts (the basis for the behavioral model of the UML) for writing the Foreword, and to my reviewers: Therese Smith, Soma Chatterjee, Sandy Friedenthal, Scott Niemann, Ben Watson, and Gary Evan for keeping me honest and helping to catch errors...ummm, I mean features, before the book went to press.
