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.

    Fantastic course. Great start for anyone interested in DAX. A Must! if you plan on becoming a BI Analyst.


    I love how Marco and Alberto explain the concepts in a simple and carefully-worded manner.

    This is super awesome. DAX is indeed simple but not easy. I gained better insight into the context transition, row and filter contexts and the importance of the CALCULATE functions. Thanks a lot.

  • Edoardo Aroni (Jul 3, 2020)

    Nowadays, it is possible to find almost everything online and probably this is also valid for this course but when you start a new learning adventure having tutors with your experience and with your personal touch provides invaluable help. I really appreciate the clear path of theory, structure learning, and re-assuring advice! Well done! Keep up with this excellent job! Thank you, Edo

  • Kishore Y C (Jul 3, 2020)

    This course has helped me to clearly understand the logic behind the DAX expressions that I am already using in my projects. This course also has introduced me to certain new functions which I will leverage well in my models. Thank you for providing this course free of cost and enabling me to handle my Power BI models in a much better way.

    Absolutely brilliant! Nothing beats to learn from the best.

  • Akila Shashith (Jul 1, 2020)

    Thanks for the amazing course. Laid good foundation for further learn DAX.

  • Christopher Moore (Jun 29, 2020)

    Great course! I've used other courses that I purchased on Udemy. They were very useful, and I learned a lot - but they went straight into DAX formulas without much theory. The background in theory on this course is fantastic, and really helps to understand what formulas to use, and why and how they work! Thank you!

    Great course, very clear content! Would be even better if you guys didn't fight to talk over the other.
