The ?rst major revision of the Uni?ed Modeling Language, UML2.0, is in the process of adoption by the Object Management Group (OMG), and it makes many long-desired additions and improvements to UML. At the same time, it expands what was already a large language. A challenge for both practitioners andresearchersistohelpsmooththeadoptionofthisnewlanguage.Increasingly, attention is being paid to the use of specialized languages, often pro?les of UML, appropriate for di?erent purposes; this is one way to make UML less overwh- ming. Accordingly, the focus of the UML conference is gradually expanding from UML to software modeling in general. Simultaneously, model-driven development is being pursued as a way of - creasing the bene?ts from modeling throughout the software development p- cess. Gradually, it is developing from a set of slogans into a reality. Many of the papers in this volume are concerned, directly or indirectly, with how to make modeling, rather than coding, the heart of software development, and how to realize the resulting bene?ts of higher-level thinking. Much work remains to be done.

For nearly ten years, the Unified Modeling Language (UML) has been the industry standard for visualizing, specifying, constructing, and documenting the artifacts of a software-intensive system. As the de facto standard modeling language, the UML facilitates communication and reduces confusion among project stakeholders. The recent standardization of UML 2.0 has further extended the language's scope and viability. Its inherent expressiveness allows users to model everything from enterprise information systems and distributed Web-based applications to real-time embedded systems. In this eagerly anticipated revision of the best-selling and definitive guide to the use of the UML, the creators of the language provide a tutorial to its core aspects in a two-color format designed to facilitate learning. Starting with an overview of the UML, the book explains the language gradually by introducing a few concepts and notations in each chapter. It also illustrates the application of the UML to complex modeling problems across a variety of application domains. The in-depth coverage and example-driven approach that made the first edition of The Unified Modeling Language User Guide an indispensable resource remain unchanged. However, content has been thoroughly updated to reflect changes to notation and usage required by UML 2.0. Highlights include: A new chapter on components and internal structure, including significant new capabilities for building encapsulated designs New details and updated coverage of provided and required interfaces, collaborations, and UML profiles Additions and changes to discussions of sequence diagrams, activity diagrams, and more Coverage of many other changes introduced by the UML 2.0 specification With this essential guide, you will quickly get up to speed on the latest features of the industry standard modeling language and be able to apply them to your next software project.

No one can dispute the impact Grady Booch's writings have had on object-oriented technology. The Best of Booch contains articles on various object-oriented topics published since Grady Booch's book Object Oriented Modeling and Design with Applications, second edition. Designed for software professionals who are concerned about the success of their object-oriented projects, this volume covers all aspects of the Booch method and how a complete method must address a model's notation and semantics as well as a process for creating that model. Many of the articles have been updated to reflect the current thinking in the Unified Modeling Language (UML).
