Ebook: The Unified Modeling Language User Guide

From the developers of UML, this tutorial reviews the core aspects of the language used to specify construct, visualize and document software-intensive systems. The authors begin with a conceptual model and progressively apply UML to increasingly complex models for a variety of applications. To derive the most benefit from this publication, you should be familiar with software engineering concepts and object-oriented modeling. After all, the author's intent is to teach you how to use UML effectively, not to go through the entire development process, or provide a reference for UML. Other publications listed below address those important issues.
