Microsoft Excel has a powerful tool called as Power Pivot that was available as an add-in in the prior versions of Excel and is built-in feature in Excel 2016. The database of Power Pivot, called the data model and the formula language that works on the data model, called DAX (Data Analysis Expressions) enables an Excel user to perform tasks such as data modeling and analysis in no time.
In this tutorial, you will learn data modeling and analysis using DAX, based on the Power Pivot data model. A sample Profit and Analysis database is used for the illustrations throughout this tutorial.
