Design Patterns Explained A New Perspective on Object-Oriented Design Second Edition By Alan Shalloway, James R Trott Publisher : Addison Wesley Professional Pub Date : October 12, 2004 ISBN : 0-321-24714-0 Pages : 480 Leverage the quality and productivity benefits of patternswithout the complexity! Design Patterns Explained, Second Edition is the field's simplest, clearest, most practical introduction to patterns Using dozens of updated Java examples, it shows programmers and architects exactly how to use patterns to design, develop, and deliver software far more effectively You'll start with a complete overview of the fundamental principles of patterns, and the role of object-oriented analysis and design in contemporary software development Then, using easy-to-understand sample code, Alan Shalloway and James Trott illuminate dozens of today's most useful patterns: their underlying concepts, advantages, tradeoffs, implementation techniques, and pitfalls to avoid Many patterns are accompanied by UML diagrams Table of Contents • Index • Building on their best-selling First Edition, Shalloway and Trott have thoroughly updated this book to reflect new software design trends, patterns, and implementation techniques Reflecting extensive reader feedback, they have deepened and clarified coverage throughout, and reorganized content for even greater ease of understanding New and revamped coverage in this edition includes Better ways to start "thinking in patterns" How design patterns can facilitate agile development using eXtreme Programming and other methods How to use commonality and variability analysis to design application architectures The key role of testing into a patterns-driven development process How to use factories to instantiate and manage objects more effectively The Object-Pool Patterna new pattern not identified by the "Gang of Four" New study/practice questions at the end of every chapter Gentle yet thorough, this book assumes no patterns experience whatsoever It's the ideal "first book" on patterns, and a perfect complement to Gamma's classic Design Patterns If you're a programmer or architect who wants the clearest possible understanding of design patternsor if you've struggled to make them work for youread this book Design Patterns Explained A New Perspective on Object-Oriented Design Second Edition By Alan Shalloway, James R Trott Publisher : Addison Wesley Professional Pub Date : October 12, 2004 Table of ISBN : 0-321-24714-0 • Contents Pages : 480 • Index Copyright Praise for Design Patterns Explained, Second Edition: The Software Patterns Series Titles in the series: Preface From Object Orientation to Patterns to True Object Orientation From Artificial Intelligence to Patterns to True Object Orientation A Note About Conventions Used in This Book Feedback New in the Second Edition Acknowledgments Part I An Introduction to Object-Oriented Software Development Chapter 1 The Object-Oriented Paradigm Overview Before the Object-Oriented Paradigm: Functional Decomposition The Problem of Requirements Dealing with Changes: Using Functional Decomposition Dealing with Changing Requirements The Object-Oriented Paradigm Object-Oriented Programming in Action Special Object Methods Summary Review Questions Chapter 2 The UMLThe Unified Modeling Language Overview What Is the UML?
