This book teaches object-oriented analysis and design through iterations of a single, cohesive case study—incrementally introducing key OO&AD skills while emphasizing practical activities and principles. Renowned object technology leader Craig Larman introduces the popular UML 1.4 diagramming notation as a superior vehicle for expressing OO&AD thoughts. Since OOA&D should be taught (and practiced) within a coherent process, he presents a lightweight, agile version of the market-leading Unified Process (UP). Within his case study's context, he also introduces patterns—robust, best-practice solutions to the most widely encountered design problems.
