Design Patterns: Elements of Reusable Object-Oriented Software (Addison-Wesley Professional Computing Series)

Of all the programming books that I've ever read, this one has had the most impact on my programming. I require that all programmers who work for me read Design Patterns.

Muy bueno, muy claro y tiene buenos ejemplos que permiten asimilar los conceptos y llevarlos a la práctica

Really makes clarity on OO programming patterns giving a complete overview and nice examples. Uses UML to describe pattern classes, sequence diagrams and collaborations. Maybe sometimes it's not so concrete in examples and keeps itself too generic.

It's a classic and a must have for the OO developer.

Good basic reference book for design patterns. The organization is NOT for reading ease, but for easy reference when you know what you're looking for to be reminded exactly what a particular pattern is all about. One sentence synopsis--Encapsulate what you expect to change.
