This is an introductory video course about the DAX language. DAX is the native language of Power BI, Power Pivot for Excel, and SSAS Tabular models in Microsoft SQL Server Analysis Services. The training is aimed at users of Power BI, Power Pivot for Excel, and at Analysis Services developers that want to move the first steps with DAX.

The goal is to teach the DAX language using Power BI for all the examples. You can download the initial Power BI Desktop file used in the demos and repeat all the steps shown in the videos. The same concepts can be used also on Power Pivot and on Analysis Services Tabular. The course is made of 150 minutes of lectures. You can watch the videos at anytime and the system will keep track of your advances. Within the course you can download the slides and the initial Power BI file used in the demos.

    Dear all, I have really reached a basic understanding of DAX. Thanks to the free course. You explained the theory really well. Because everytime you talked about what you tried to reach first and then, step-by-step, showed the elements needed to accomplish just that within DAX, the course was easy to follow. I have even already succeeded in building a couple of functions myself. Thank you very much for your efforts. I am really gratefull.

    The course is easy to follow and things are explained so that I can understand. I am seeing some things I have done wrong before and will use my new learning. This course makes me want to take the master course in Dax. I really enjoyed this course. David, Sweden

    Many thanks for this useful course.

  • Noorul Sarodia (Nov 18, 2019)

    Really good course, the first time I understood measures and calculated columns (one calculates across and one calculates downwards - I hope!) after six months of playing with PBI.

  • Dariusz Olak (Nov 17, 2019)

    Fantastic. Although I already made some advance in using Power BI and DAX, the course let me understand what I comprehended intuitively so far. It helped me unscramble my understanding of DAX functions and algorithms.
