While MDX is modeled after SQL (SELECT…FROM…WHERE), DAX was designed for use by business and data analysts already familiar with Excel functions. In some ways, it is a happy medium between Multidimensional Expressions (MDX) and Excel functions. We can use DAX to create columns, measures, and query the database.

In this chapter, you will learn all there is to know about DAX, which will help you to enhance your existing models to meet the business requirements. Without the calculations you create with DAX, the user experience with the models will not be as good as it could be. DAX calculations allow your users to have business-ready calculations at their fingertips. Without these calculations...
