UML distilled - Martin Fowler

The award-winning first edition of UML Distilled was widely praised for being a concise guide to the core parts of the UML and has proved extremely successful in helping developers identify the most important parts of the language. UML Distilled, Second Edition, maintains the concise format with significantly updated coverage of use cases and activity diagrams, and expanded coverage of collaborations. It also includes a new appendix detailing the changes between UML versions. Beginning with a summary of UML's history, development, and rationale the book moves into a discussion of how the UML can be integrated into the object-oriented development process. The primary author profiles the various modeling techniques in the UML--such as use cases, class diagrams, and interaction diagrams--and describes the notation and semantics clearly and succinctly. He also outlines useful non-UML techniques such as CRC cards and patterns.
