The Definitive Guide to DAX

The Definitive Guide to DAX (Business intelligence with Microsoft Excel, SQL Server Analysis Services, and Power BI) is the most comprehensive and authoritative guide to Microsoft’s DAX language for business intelligence and analytics. While other books cover only the basics, this guide offers expert guidance on everything intermediate-to-advanced Excel users and BI professionals need to know, from the basics to innovative high-performance techniques.

Two leading Microsoft BI consultants and mentors introduce DAX through realistic and useful examples, presenting common calculations that empower users to get results immediately. Alberto Ferrari and Marco Russo demystify complex topics, showing readers exactly what happens under the DAX engine’s “hood” when they run a DAX expression. Ferrari and Russo carefully walk through common scenarios where DAX may not be easy to grasp; show how to optimize data models so DAX expressions will run quickly; demonstrate how to write fast, robust DAX code; and guide you in clearing bottlenecks from existing code. Throughout, they demonstrate DAX at work in both SQL Server and Microsoft Excel environments, empowering you no matter which Microsoft BI or analytics platform you prefer.

The best DAX resource, I have been waiting for a long

Tamas Polner wrote:

I have been looking forward for this book to be available for shipment. Alberto and Marco’s previous books were my 101’s into self service BI, but after finishing them, the only resource to go deeper were only available in different online sources. I think this book is definitely a must have for all BI professionals. They are great in explaining even the most difficult concepts, and the material in this book is very much up-to-date with the new Power BI Service and Power BI Desktop.

I have to admit, it felt like this book was written specifically for me

I have been really looking forward to reading The Definitive Guide to DAX by the fine folks we lovingly refer to as “The Italians”, Marco Russo and Alberto Ferrari. At over 500 pages, I still jammed through it in about one week… and now I am hear to let you know if it was worth my time. Spoiler: It was bad ass.
I’m not going to go into a ton of detail about the contents of the book, as you can go look at the table of contents on Amazon. I will say that the contents of the book were exactly what I expected – a deeply technical book on DAX dealing with the nitty gritty details over filter context, context transitions, details of the xVelocity (aka Vertipaq) engine, performance tuning, and general 400+ level topics, This ain’t no sippin’ tea! (I have no idea what I meant by that, just go with it).

A DAX book aimed at taking people from intermediate to expert

Austin K Senseman wrote:

Wow! I make a good part of my living off of Power Pivot and DAX and it’s people like Alberto and Marco that have helped me all along the way – with their blog posts, conference sessions, and books. This book really stands out though. It’s a very complete treatment of DAX which is the core language of all the “new” analytical tools that Microsoft has released over the past three years.

Truly the definitive guide, I highly recommend

Matthew Brice wrote:

If you really want to know and understand how Dax works, then this is the book you want. It is definitely not for beginners but rather delivered a tremendous amount of both breadth and depth about Power Pivot and more specifically Dax. Having read and viewed the whitepapers, blogs and presentations from the authors the book was exactly what I was expecting and wanting.
