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.

To get the most out of this book

As mentioned, in this book we assume that you already have practical experience with DAX and are looking to extend your knowledge, applying DAX to a range of more complex scenarios. For this reason, we do not generally explain the way a DAX function and its arguments are used, unless we need to for a specific case; this information can easily be found on the internet.

All models can be found on the book's GitHub site at https://github.com/PacktPublishing/Extreme-DAX. Each chapter contains a link to the PBIX file(s) used in the chapter. We recommend that you use the PBIX files to help you follow along with the chapters.

You can use the latest version of Power BI Desktop to open the PBIX files. When relevant, each figure in a chapter, representing a visualization and the code used, can be found in the PBIX file.

Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates DAX expressions in the text. For example: "The inactive relationship will save us a lot of ALL('Calendar') clauses in our DAX code."

A block of code is set as follows:

Total Sales = 
CALCULATE(
    SUM(fProjectSales[Budget]),
    USERELATIONSHIP(fProjectSales[StartDate], 'Calendar'[Date])
)

When we wish to draw your attention to a particular part of the text, the relevant lines or items are set in italics. For instance: "Note that we made the relationship between fProjectSales and Calendar inactive. This is done because most calculations will probably not group projects by their start date, but spread results over a period of time beginning with the start date of a project."
