There are amazing books on DAX, Power Query, Visualisations, and more. This book is the one you should read before reading those. I wanted this book to cover the whole Power BI experience. Starting with Power Query, moving to data modeling, DAX, publishing and sharing, report design, and other additional important features. Mastering Power BI is a multi-year journey but learning the best practice principles from this book will give you a jump start and a solid foundation on which to build.
