The first edition of Applying UML and Patterns: An Introduction to Object-Oriented Analysis and Design quickly emerged as the leading OOA/D introduction; translated to manylanguages and adopted in universities and businesses worldwide. In this second edition, well-known object technology and iterative methods leader Craig Larman refines and expands this text for developers and students new to OOA/D, theUML, patterns, use cases, iterative development, and related topics. The book helps newcomers to OOA/D learn how to think in objects by presenting three iterations of a single, cohesive case study, incrementallyintroducing the requirements and OOA/D activities, principles, and patterns that are most critical to success. It introduces the most frequently used UML diagramming notation, while emphasizing that OOA/D is much more than knowing UMLnotation. All case study iterations and skills are presented in the context of an agile version of the Unified Process -- a popular, modern iterative approach to software development. Throughout, Larman presents the topics ina fashion designed for learning and comprehension. Among the topics introduced in Applying UML and Patterns are: * requirements and use cases, * domain object modeling, * core UML, * designing objects with responsibilities, *Gang of Four and other design patterns, * mapping designs to code (using Java as an example), * layered architectures, * architectural analysis, * package design, * iterative development, * the Unified Process.Foreword byPhilippe Kruchten, the lead architect of the Rational Unified Process.
