This is the worst Dynamics AX 2009 book I've seen yet, and they're all pretty bad. There is no information whatsoever in this book that you can't get from MSDN or the Dynamics AX sales team. Like most Microsoft Dynamics AX documentation this book only gives descriptions of features or functions in AX. There are no explanations of how to use any of it. The book is worthless. It was written by the Microsoft Dynamics AX team and for the Microsoft Dynamics AX team. If you don't already know what you need to know about AX this book will not help you.

This book is good for understanding AX 2009, if you are first timer. It is a good reference in my library for AX 2009. Also the fact is that this is the only technical book on AX 2009 available, apart from 2 functional ones (supply chain and manufacturing). The first chapter 'architectural overview' is not very well written. Apart from that book is pretty good. I give this book 5 stars as this book is helping me get into AX 2009 and preparing me for my AX 2009 development certification.
