Data Analysis Expressions, DAX, is the language of Power BI, Power Pivot, Excel Data Models, and SQL Server Analysis Services (SSAS) Tabular Mode. Five videos are free to watch! The remaining, full-length, demo-rich tutorials, over 6 hours in total, by Alberto Ferrari and Marco Russo, are available for purchase.
Please note, this course focuses on an older version of DAX dated pre-2015. If you use Excel 2013 or SharePoint, or SQL Server 2014, this course is applicable to you. We also offer a newer, in-depth course on DAX, especially useful if you prefer to use the Power BI Desktop: Mastering DAX Workshop.
