Design Patterns by Erich Gamma, John Vlissides, Ralph Johnson, Richard Helm (1997, Hardcover)

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.

Four top-notch authors present the first book containing a catalog of object-oriented design patterns. Readers will learn how to use design patterns in the object-oriented development process, how to solve specific design problems using patterns, and gain a common vocabulary for object-oriented design.

Industry Reviews
"Design Patterns is a real eye-opener: If you've ever read a programming book that was just filled with amazing tricks and tips, you'll feel a bit of deja vu with this analogue for designers."
Dr. Dobb' s Journal - Warren Young (10/19/1996)
