Overview of this book

This book helps business analysts generate powerful and sophisticated analyses from their data using DAX and get the most out of Microsoft Business Intelligence tools. Extreme DAX will first teach you 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. You’ll also be provided with PBIX files for each chapter, so that you can follow along and explore in your own time.

The digital transformation cycle

So far, we have focused on what is needed to go from "raw" data to insights, and the role of DAX-powered Power BI models in this process. We have seen that business value does not come from merely connecting and preparing data, but that it is the insights from visual, interactive reports that provide value.

However, no organization will get better from just staring at nice-looking reports. What really matters, of course, is what you do with the insights. In other words: you need to take action to reap the benefits of a BI solution. You will also want to measure the effects of these actions, either in an automated way or by letting users enter feedback into some kind of system. The result of that is, again, data.

This leads to a cycle of digital transformation, or data-driven business improvement:
