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.

Grady Booch、James Rumbaugh和Ivar Jacobson是UML的創始人，均為軟件工程界的權威，除瞭著有多部軟件工程方麵的著作之外，在對象技術發展上也有諸多傑齣貢獻，其中包括Booch方法、對象建模技術（OMT）和Objectory（OOSE）過程。目前Booch和Rumbaugh在IBM工作，Jacobson是獨立谘詢師。
