This book uses the naming pattern of a book that changed the world in Object Oriented Development (to those who can't make the connection, I'm referring to the GoF book "Design Patterns"). Unfortunately, this book won't change the world of Integration Services.
It's a very good book that explains how SSIS works, but does nothing different than all those other books. I started reading this book expecting to find some genius solutions to problems I've encountered, but no. I found the same old problems and the same old solutions. Don't get me wrong. This book is good compared to other supposed "Professional" SSIS books. This book is INDEED a professional book about SSIS, but that "Design Patterns" title builds a lot of expectations that I was disappointed after reading it.
I would recommend this book to someone that knows the basics of SSIS and needs to know how to apply these basics to real world problems.
