This book constitutes the refereed proceedings of the 6th International Conference on the Unified Modelling Language, UML 2003, held in San Francisco, CA, USA in October 2003. The 25 revised full papers, 4 tool papers, and 1 experience paper presented together with the abstracts of 3 invited talks and summaries on the UML 2003 workshop and tutorials were carefully reviewed and selected from initially 168 submissions. The papers are organized in topical sections on practical model management, time and quality of service, tools, composition and architecture, transformation, Web related issues, testing and validation, improving UML/OCL, consistency, and methodology.

Thepastyearhasbeenaneventfuloneforthoseinterestedinsoftwaremodeling. 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.

With its clear introduction to the Unified Modeling Language (UML) 2.0, this tutorial offers a solid understanding of each topic, covering foundational concepts of object-orientation and an introduction to each of the UML diagram types.

This book constitutes the refereed proceedings of the 7th International Conference on the Unified Modeling Language, UML 2004, held in Lisbon, Portugal, in October 2004. The 30 revised full papers presented together with summaries on the workshops and tutorials were carefully reviewed and selected from 135 technical paper submissions. The papers are organized in topical sections on metamodeling, aspects, profiles and extensions, OCL, model transformation, verification and model consistency, security, and methodology.

This book constitutes the refereed proceedings of the 8th International Conference on Model Driven Engineering Languages and Systems (formerly the UML series of conferences), MoDELS 2005, held in Montego Bay, Jamaica, in October 2005. The 52 revised full papers and 2 keynote abstracts presented were carefully reviewed and selected from an initial submission of 215 abstracts and 166 papers. The papers are organized in topical sections on process modelling, product families and reuse, state/behavioral modeling, aspects, design strategies, model transformations, model refactoring, quality control, MDA automation, UML 2.0, industrial experience, crosscutting concerns, modeling strategies, as well as a recapitulatory section on workshops, tutorials and panels.
