Supercharge Power BI: Power BI is Better When You Learn To Write DAX

I have a strong Excel and Access background. This book worked well for me. It is easy to follow and has good practice exercises.

This book provides a sample database and works you through a long list of basic function examples. The author was very methodical and complete in his instructional methodology. It is he best book I have purchased for entry-level DAX and a bit beyond.

I spent about a year learning how to use Power BI by reading blog posts and watching YouTube videos. It wasn't until I read this book that it all finally clicked. In fact, I would say that if I had read this book on day one, it would have saved me about a year of fumbling around!Matt has a very down-to-earth teaching style. His lessons are very practical, and I love that he has plenty of exercises to test your knowledge right after he introduces a new topic (complete with answers at the end of the book). He says many times in the book that you need to complete the exercises to understand the material, and that just reading isn't enough. I believe him!I originally learnt from the second edition of the book, but I bought this third edition about a year later for a refresher. The page count has increased from 186 to 288.I thought the 2/e did a great job of teaching the material, but the extra 100 pages in the 3/e really helped flesh out the concepts. I found myself nodding along at the explanations, and was particularly impressed with his descriptions of how the DAX engine works and how best to think through the calculations.Matt really stuffs a lot of tips and best practices in this book. You can tell that he regularly teaches this material to students in the way that he has honed his explanations and analogies between editions.If you are using this book to self-study, I would say that on the first read through you are likely to internalize ~85% with some practice. Come back 3 months later, and you'll find the remaining ~15% finally makes sense and cements your knowledge.In summary, I think this is the best book I've read so far in introducing Power BI to a new user. It's also a fantastic book to re-read after you've been practicing your skills for a few months.Kudos, Matt!

This book is an excellent resource to learn about PowerBI and DAX. By the end of the book, I was able to create my own DAX formulas without having to reference earlier chapters. I would recommend this book to anyone interested in learning DAX. The examples and projects in this book are well written and easy to follow.

This book makes an EXCELLENT companion book to Rob Collie & Avichal Singh's book on Power Pivot and Power BI. But that's not to say that this book can't stand on it's own. If you have to pick just one "bootstrap yourself on DAX" book, this would be an very good pick. While Collie & Singh's book gives a bit more of a technical explanation of these tools, Allington actually walks you through, step-by-step, showing you how to develop increasingly complex DAX expressions using the Power BI interface, not the Excel/Power Pivot interface. This means that Allington shows you some visuals and other nuances that are not in Excel or that might be hard to find if you are coming from Excel. Interwoven with these examples are great insights as to how the various functions work and why you need to "do it this way" in DAX, very helpful if your primary formula-writing experience is Excel-based. The 3rd addition's information, screenshots, etc. is pretty current (as of Fall of 2021).

Matt is a great writer and Power BI Professional. I recommend this book for beginning users of Power BI and professionals who have been using it for a couple years. Well done Matt.

After reading this book, I can hold my own in any power bi conversation. The book is great at explaining the "why" in easy to understand terms. It also does a great job at explainIng best practices for setting up your data.What I like most is the author quickly explains a concept and then gives you a practice session to try it out. It's great if you learn by doing. This truly is more of a workbook than a textbook.This has been the only resource I've found to use this format for dax. I only wish there was a second version for more complicated measures.

Si estás buscando un libro que te explique las bases para entender Dax… este lo es! Usa un lenguaje sencillo con ejemplos claros. Voy por la mitad del libro pero debo de decir que he cubierto muchos conceptos básicos que me hacían faltan para entender verdaderamente Dax.
