"This book is an important contribution to practicing object designers and developers! Have you ever tried to describe an idea that you don't have a precise name for? It can be frustrating. Design Patterns organizes and presents a catalog of proven design idioms for structuring, creating, and manipulating objects. Most importantly, it names these design constructs, allowing teams to share a common vocabulary."
— Rebecca /. Wirfs-Brock, Director, Object-Technology Services, Digitalk
"Design Patterns leaves the debates about code reuse behind and shows the real key to software reuse: reusable design. You'll find yourself applying and reusing these patterns in your own designs in no time."
— Steve Vinoski, Software Architect

" [Design Patterns] makes two important contributions. First it shows the role that patterns can play in architecting complex systems. Second, it provides a very pragmatic reference to a set of well-engineered patterns that the practicing developer can apply to crafting his or her own specific applications."
— from the Foreword by Grady Booch, Chief Scientist, Rational
Capturing a wealth of experience about the design of object-oriented software, four top-notch designers present a catalog of simple and succinct solutions to commonly occurring design problems. Previously undocumented, these 23 patterns allow designers to create more flexible, elegant, and ultimately reusable designs without having to rediscover the design solutions themselves.
The authors begin by describing what patterns are and how they can help you design object-oriented software. They then go on to systematically name, explain, evaluate, and catalog recurring designs in object-oriented systems. With Design Patterns as your guide, you will learn how these important patterns fit into the software development process, and how you can leverage them to solve your own design problems most efficiently.
Each pattern describes the circumstances in which it is applicable, when it can be applied in view of other design constraints, and the consequences and trade-offs of using the pattern within a larger design. All patterns are compiled from real systems and are based on real-world examples. Each pattern also includes code that demonstrates how it may be implemented in object-oriented programming languages like C++ or Smalltalk.
