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

This book starts from the basics. It takes you through a structured journey, building on new concepts slowly but in a natural way. For newbies to PBI, read this to get a solid foundation from which you can then build up. This book has loads of practice exercises ,ensuring you get a good grounding. Don't waste more time starting with YouTube videos: learn PBI in a structured way and you'll thank yourself later. Thank you Matt for sharing your knowledge, you're the best teacher for newbies.

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.

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

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!

I use this textbook in my master of accountancy program.

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.

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'm a heavy Power BI and Power Pivot user. For awhile, I’ve been familiar with many DAX functions. But now, I have a much better idea of what’s going on “under the hood”. For example, I didn’t know about CUBE formulas or the concept of Context Transition. And now, I’m better able to integrate #PowerBI, #PowerPivot and #Excel. I highly recommend this book to anyone working with BI using Excel, Power Pivot, or Power BI.

Ich hatte mich dem Thema Power BI über diverse Lernplattformen und Online Tutorials z.B. bei Youtube angenähert. Im Anschluss daran hatte ich zwar ein Grundverständnis, wie Datenimporte funktionieren und Daten transformiert werden können und auch, wie Visuals erstellt werden, aber ein wirklich tiefgehendes Verständnis hatte ich nicht. Bei jedem neuen Measure war ich froh, auf ein schon bekanntes Measure zurückgreifen zu können, und mit viel Ausprobieren ein abgeändertes Measure hinzubekommen, was irgendwie die richtigen Daten produziert hat. Mühselig! Das alles hat sich nach der Lektüre dieses Buches grundlegend verändert. Ich sag mal so: "Ich weiß jetzt Bescheid!" Wahrscheinlich ist das Buch nichts für Menschen, die ganz neu mit Power BI anfangen, aber das wird glaube ich auch so gesagt. Für Menschen mit Vorwissen ist es dagegen eine Fundgrube an grundlegenden Informationen zu DAX-Funktionen und ihrer Syntax. Immer wieder schafft es der Autor, das neu gezeigte Wissen in den größeren Kontext zu setzen und damit fest im Verständnis des Lesers zu verankern. Toll! Abgerundet werden die 5-Sterne dadurch, dass das Buch außerdem auch extrem gut lesbar ist, teilweise blitzt sogar so etwas wie Humor auf (soweit das bei so einem Thema überhaupt geht...). Das Englisch ist auch für Nicht-Muttersprachler nicht zu fordernd und meiner Meinung nach für jeden sehr gut machbar, der sich regelmäßig bei seiner Arbeit mit Daten und ihrer Verarbeitung beschäftigt. Das Buch ist für mich ein echter Gewinn!

Nice lessons builds up your skills verfy quickly. Best tips are around navigation within Power BI. Saving a lot of development time now as a result.

I am new to PBI and wanted to know more about DAX and this book was great for it. Although it is intended for Excel expert users, which I am not, I still found it very easy to follow and well explained. I bet it is even better for those out there who know Excel very well because there are many references and comparaison to it. Funny point about this book, which I kinda liked, is that it's written as if the author is speaking to you. You can almost hear him talking and it makes it friendlier and easier to understand compared to super formal writing. Especially if, like me, English is not your first language. I ordered the paper book because, being a visual learner, I like to highlight, comment and circle stuff. The font is big enough (10-12 pt?) and the book is 8.5 x 11 in.

It's my first Dax book. I thoroughly enjoyed Dax through this book. Ample amount of demonstrations and relevant exercises.
