Book Description

If you want to get the most out of Microsoft Business Intelligence tools, sooner or later you'll need to master DAX. Extreme DAX enables business analysts to generate powerful and sophisticated analyses from their data.

You'll learn the principles of business intelligence, good model design, and how DAX fits into it all. Then, you'll launch into detailed examples of DAX in real-world business scenarios such as inventory calculations, forecasting, intercompany business, and data security. At each step, senior DAX experts will walk you through the subtleties involved in working with Power BI models and common mistakes to look out for as you build advanced data aggregations.

You'll deepen your understanding of DAX functions, filters, and measures, and how and when they can be used to derive effective insights. Also provided with the book are PBIX files for each chapter for you to follow along with and explore in your own time.
