The theory of architecture implicit in our world today, Christopher Alexander believes, is bankrupt. More and more people are aware that something is deeply wrong. Yet the power of present-day ideas is so great that many feel uncomfortable, even afraid, to say openly that they dislike what is happening, because they are afraid to seem foolish, afraid perhaps that they will be laughed at. Now, at last, here is a coherent theory which describes in modern terms an architecture as ancient as human society itself.

《UML和模式应用》(英文版第3版)介绍了“对象思想”，并在实际的面向对象分析和设计中应用了这一思想，即如何以对象进行思考和设计，以及如何创建精致、健壮和可维护的系统。开发者和学生可以通过贯穿全书的两个案例研究的三个迭代来学习面向对象分析和设计（OOA/D），这两个案例研究增量地介绍了关键技能、OO的本质原则和模式、UML表示法和最佳实践。读者不仅可以从中学习到UML图，更重要的是可以学习到如何在OO软件开发环境下应用UML。享誉世界的崭新版本，面向对象分析与设计及UML的介绍。全面升级到UML 2和最新的迭代/敏捷实践。增加了全新的案例研究，阐述了大量关键思想。无论对于专业人士还是教师来说，《UML和模式应用》(英文版第3版)都堪称世界一流。书中介绍了“对象思想”，并在实际的面向对象分析和设计中应用了这一思想，即如何以对象进行思考和设计，以及如何创建精致、健壮和可维护的系统。开发者和学生可以通过贯穿全书的两个案例研究的三个迭代来学习面向对象分析和设计（OOA/D），这两个案例研究增量地介绍了关键技能、OO的本质原则和模式、UML表示法和最佳实践。读者不仅可以从中学习到UML图，更重要的是可以学习到如何在OO软件开发环境下应用UML。 基于广受赞誉的前两版，本版进行了修订，充分反映了新的UML 2标准，提倡了具有高度影响的、迭代的和有效的敏捷建模实践，有助于读者掌握对象设计，理解进化式需求和用例、领域对象建模、职责驱动设计、OO设计本质、分层架构、“四人帮”设计模式、GRASP、迭代方法、UP的敏捷途径等。

You're not alone. At any given moment, somewhere in the world someone struggles with the same software design problems you have. You know you don't want to reinvent the wheel (or worse, a flat tire), so you look to Design Patterns--the lessons learned by those who've faced the same problems. With Design Patterns, you get to take advantage of the best practices and experience of others, so that you can spend your time on... something else. Something more challenging. Something more complex. Something more fun. You want to learn about the patterns that matter--why to use them, when to use them, how to use them (and when NOT to use them). But you don't just want to see how patterns look in a book, you want to know how they look "in the wild". In their native environment. In other words, in real world applications. You also want to learn how patterns are used in the Java API, and how to exploit Java's built-in pattern support in your own code. You want to learn the real OO design principles and why everything your boss told you about inheritance might be wrong (and what to do instead). You want to learn how those principles will help the next time you're up a creek without a design paddle pattern. Most importantly, you want to learn the "secret language" of Design Patterns so that you can hold your own with your co-worker (and impress cocktail party guests) when he casually mentions his stunningly clever use of Command, Facade, Proxy, and Factory in between sips of a martini. You'll easily counter with your deep understanding of why Singleton isn't as simple as it sounds, how the Factory is so often misunderstood, or on the real relationship between Decorator, Facade and Adapter. With Head First Design Patterns, you'll avoid the embarrassment of thinking Decorator is something from the "Trading Spaces" show. Best of all, in a way that won't put you to sleep! We think your time is too important (and too short) to spend it struggling with academic texts. If you've read a Head First book, you know what to expect - a visually-rich format designed for the way your brain works. Using the latest research in neurobiology, cognitive science, and learning theory, Head First Design Patterns will load patterns into your brain in a way that sticks. In a way that lets you put them to work immediately. In a way that makes you better at solving software design problems, and better at speaking the language of patterns with others on your team.

The practice of enterprise application development has benefited from the emergence of many new enabling technologies. Multi-tiered object-oriented platforms, such as Java and .NET, have become commonplace. These new tools and technologies are capable of building powerful applications, but they are not easily implemented. Common failures in enterprise applications often occur because their developers do not understand the architectural lessons that experienced object developers have learned. Patterns of Enterprise Application Architecture is written in direct response to the stiff challenges that face enterprise application developers. The author, noted object-oriented designer Martin Fowler, noticed that despite changes in technology--from Smalltalk to CORBA to Java to .NET--the same basic design ideas can be adapted and applied to solve common problems. With the help of an expert group of contributors, Martin distills over forty recurring solutions into patterns. The result is an indispensable handbook of solutions that are applicable to any enterprise application platform. This book is actually two books in one. The first section is a short tutorial on developing enterprise applications, which you can read from start to finish to understand the scope of the book's lessons. The next section, the bulk of the book, is a detailed reference to the patterns themselves. Each pattern provides usage and implementation information, as well as detailed code examples in Java or C#. The entire book is also richly illustrated with UML diagrams to further explain the concepts. Armed with this book, you will have the knowledge necessary to make important architectural decisions about building an enterprise application and the proven patterns for use when building them. The topics covered include * Dividing an enterprise application into layers * The major approaches to organizing business logic * An in-depth treatment of mapping between objects and relational databases * Using Model-View-Controller to organize a Web presentation * Handling concurrency for data that spans multiple transactions * Designing distributed object interfaces
