This book teaches DAX in an approachable and well written way that leads the user to join along and work through the examples. DAX is certainly a language best learned while doing, rather than memorizing, and this book does a great job of supporting that method. I will certainly be recommending this book to all new users that want a great jump start and solid base in DAX. It will certainly help in expanding their capabilities and drive them towards producing better insights in their reporting efforts in Power BI.
Beginning DAX with Power BI is an excellent resource for all Power BI users, whether complete beginners or more advanced.
Phil Seamark presents DAX in all its glory, from basic definitions and examples to some quite advanced applications. The examples provided clearly reflect a wealth of experience as a Power BI practitioner, and will be relevant to a wide range of Power BI users.
The core concepts are covered excellently, including the data model, context and filtering. There are some great examples of table functions and emphasis on the power of DAX as a query language.
I was also pleased to see coverage of such practical topics as debugging & optimizing, code formatting and variables!
While I consider myself reasonably experienced with DAX, I gleaned a number of useful techniques from this book, and found myself repeatedly saying "aha" as I read through. I will be referring to this book for years to come!
This is the first book I read about DAX (and I have read a lot) that provides a concise and first of all an easy to read introduction into the mysterious FILTER CONTEXT. It also covers the latest development of DAX by comparing different functions that have surfaced over time and are doing more or less all the same, summarizing a table, but Phil explains their own twists. Phil provides great examples when to use which of the summarizing functions like SUMMARIZE, SUMMARIZECOLUMNS, or GROUPBY.
Another great chapter is about JOINS, emphasizing the importance of relationships.
Personally I consider myself an expert in the field of DAX, but I found some new ideas and approaches reading this book.
This will be the recommendation in all my DAX trainings.
It was a fun read!
Phil does an amazing job of starting off with the easier DAX examples, and then going into more complex DAX requirements. The flow of the book from simple to more complex DAX was seamless and took me on a journey where I learnt many new things in DAX.
I have already started referring to this book when working daily to get those nuggets of gold that Phil has in his book.
I would happily recommend this book to anyone looking to get a better understanding of DAX, and even to the seasoned DAX professional this is an excellent resource.
