Mastering DAX Video Course

This is the video course version of the Mastering DAX workshop.
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 learn and master the DAX language.

The goal of the course is to teach all the features of DAX, providing the knowledge to write formulas for common and advanced business scenarios. The video course is made up of over 15 hours of lectures, plus another 15-20 hours of individual exercises. You can watch the videos at anytime and the system will keep track of your progress. Within the course you can download the material for all the exercises.

Students have access to a private discussion area where they can interact with the instructors asking questions related to the lectures and the exercises.

  • Zhongxue Li (Dec 7, 2023)

    Well organized, very informative and the examples/excises are helpful while progressing the course. Thank you!

  • Arisha Khamitova (Nov 29, 2023)

    Very broad explanation for some formulas DAX. However, there are some features and solutions to them that are outdated. In some case it is dificult to understand the content due to not understanding well the meaning of some words such as filter context, iterators etc. I think there should be some vocabularly or introduction to this specific words.

  • FERNANDO CAPACE (Jun 7, 2023)

    Dense but good!

  • Frank Peeters (Apr 4, 2023)

    Great course, have to do it a few more times to master everything.

  • Francisco Fuerte (Jul 12, 2022)

    Muy buen contenido.

  • Martina Voigt (Apr 13, 2022)

    It is okay.

  • Coro Lamoré (Jun 18, 2021)

    Clear explanation of the different DAX items. It has helped me create dax formulas. The difficulty for me now is to make DAX formulas that have nothing to do with Sales, but with analysis of delivered products of technical modifications per engineering department. I just have to figure it out, because there is no one in the department who can help me with DAX, but during the course I was already able to apply it in practice.

  • Wout Kattenpoel (Sep 14, 2020)

    Great course with a great attention to detail and a easy to follow step-wise learning module. The explanations of the presenters are very clear. The excercises however often included subjects and code of future lectures, that made some excercises nearly impossible to solve with the current knowledge. This demotivates a bit, as solving excercises correctly makes you want to continue, whereas continuous struggling with the excerices is a tad annoying.

    • Hi Wout, just a clarification: the Advanced exercise we have in the initial chapters have been included for people who start the course with existing knowledge of DAX. For this reason, they have additional prerequisites. Only the Basic exercise should be completed with the knowledge provided in each section, the Advanced one should be considered optional. We included them because we had the request for more challenging exercises in the initial sections. However, we have to better explain this in the video course, we are working on that and it should be fixed soon. Thanks for your feedback!

  • Andradhige Tharindhu Anuradha (Aug 17, 2020)

    Finally I am done. Learned a lot of DAX concepts. Thanks

  • Jonathan Owney (Aug 13, 2020)

    This is the most comprehensive course you will find on DAX anywhere. I found it helps to read along in the book ("The Definitive Guide to DAX") and then watch the videos as I go. The book mirrors the course content and order almost exactly. The one thing I hope they improve on are the exercises. For most modules there are one to three exercises but for some there are none. I would definitely understand the content and retain the knowledge better if there were more examples to work out for each module. While some people who take this course can apply the knowledge directly to there work others, like myself, don't work with DAX in our days jobs but eventually want to so the more exercises we can try the better. It could even benefit from quiz's along the way and a test at the end.

  • John Nickell (May 16, 2020)

    I think it's been a good course, and that Marco and Alberto do a great job explaining DAX. I'm still not fluent, but feel slightly better equipped to go forward.

  • Udit Chatterjee (May 7, 2020)

    The courses are indeed the masterpiece and excellent but, please fix the site. Its very slow and works poorly if the internet speed is little low. Fix the site please, this is the only demerit I find and that's why rating this 4 star but, again the courses are excellent and so as the instructors.

    • Please, can you provide more details about your issues? Most of the time that a user experiences a problem with the videos, it is because of a firewall or an antivirus that slows down the connection. You can lower the resolution of the video to reduce bandwidth consumption if your internet connection is slow. If you experienced other issues, please clarify so we can investigate. Thanks for your feedback!

  • Ryan Park (Jan 15, 2020)

    This course is the most comprehensive course I could find regarding DAX. Here a couple of opinions. There only needs to be 1 instructor per section and the instructor does not need to be in the video. It would be nice to see the slides and the computer screen without the instructor obstructing the view. You would also benefit from not having to rely on the other instructor to fit the screen or go back to a function, etc. It feels like you are stepping over each other a lot. I feel like you are trying to make the questions seem natural but it doesn't work. Outside of that. Excellent course.

  • Alison Sissins (Nov 1, 2019)

    Very thorough in depth course. It can be confusing with all the scenarios and solutions but this is what it's like using DAX for real.

  • CAROLINE NDUTA (Sep 5, 2019)

    I have just finished my course only to find out that I have only done 97% How do I locate the 3% not covered?

    • You should check in your course what are the lessons that are not marked as "completed" - you can change them manually (maybe the browser did not send the notification for some video you already watched).
