Holub on Patterns, Fachbücher

This is a book about programming in an object -oriented way and about how to use design patterns to solve commonplace problems in object-oriented systems. I've based this book on the philosophy that the best way to learn and understand the design patterns is to see them in action, all jumbled up, just as they occur in the real world. Consequently, this book presents design patterns to you by looking at computer programs. My intent is to both clarify and bring down to earth Gamma, Helm, Johnson, and Vlissides's seminal work Design Patterns: Elements of Reusable Object-Oriented Software (Addison-Wesley, 1995). (The four authors are often called the Gang of Four [or GoF], and their book is usually called the Gang-of-Four book.) The current volume puts the GoF book into context, presenting and teaching design patterns as they occur in the real world. By the time you're done, you'll have seen.
