Data Modeling for Power BI Video Course

Data modeling is a required skill to get the most out of Power BI, Power Pivot for Excel, and Analysis Services. This video course is aimed at users of Power BI Desktop or Power Pivot for Excel, and at Analysis Services developers who want to learn how to build the optimal data model for their reporting needs.

The goal of the video course is to teach through examples of increasing complexity how to solve business scenarios by adapting the data model, so that the required DAX code becomes easier, faster and more robust. All the demos and the exercises are based on Power BI examples. However, the very same concepts can be applied to Power Pivot and Analysis Services Tabular.

The video course is made up of over 10 hours of lectures, plus another estimated 8 hours of individual exercises. You can watch the videos at any time and the system will keep track of your progress. Within the video 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.

    great course, thank you!

  • Carlos Gonzalez Seco (May 7, 2021)

    The course is not simply easy to follow, due to continous explanations and relationships that are referring to something else we cannot see. More hours should have been dedicated to basic level, to reinforce the important concepts. Too condensated, at least double of hours minimum would be required for the course, splited up into more basic examples. Too many concepts and complexity on a few hours. It is mentioned that DAX is not requirement, but finally it shows up everywhere, being really complex/impossible for beginners.

  • Elizabeth Nachmin (Feb 18, 2021)

    Great content and explained very well. Recommend this course for every PowerBI developer. Thanks a lot

  • Kristof Sender (Jan 7, 2021)

    It was sold to us by mention you don't need to have any expirience in advance. this is not correct. the course speed is just to fast to understand and deploy the topics. unfortunatly this has been a waste of time so far. I would recommend you need to have at least to teach the basics first!

    • As discussed, the Data Modeling course is not a beginner course and we do not promote it as a beginner course. We always encourage students to follow the learning path we have designed. It is a good idea to start with the two free introductory courses, to then fully benefit from the Data Modeling course.

    Great course specially the currency and the budget modules insights.

  • Rich Brown (Dec 30, 2020)

    A little too advanced for me. I will need to review the introduction course, then go back through this one.

  • Anna Kolbasova (Nov 15, 2020)

    Thank you so much for the course!!! I've learned many useful scenarios that I will definitely check in practice. When I complete "Mastering DAX", which is my next course, I'm going to return to some complex topics from "Data Modeling" course to get a better understanding of DAX formulas.

  • Rafał Sromek (Nov 12, 2020)

    Great course in DAX. Too bad that it lacks explanation of Power Query Editor and M.

  • Dirk Martinschledde (Nov 3, 2020)

    Very good course for data modeling in Power BI with many practical examples. Keep it up!

  • Laurence Gerard (Nov 1, 2020)

    Very thorough course. I have a much better understanding now of data modeling.

  • Irshad Kuttoor Illam (Sep 16, 2020)

    Nice.. I have to go back to each Lectures in detail again to achieve my goals. Thank you Marco Russo & Alberto Ferrari for your incredible efforts.

  • Klaus Trampedach (Sep 12, 2020)

    Very good course if you want to understand the importance of having the right data model. This makes your DAX-life so much easier! :)

  • Jorge Daniel (Aug 28, 2020)

    This is my second course with you and I learned a lot from this one as well. To me Alberto and Marco, are like the Francesco Totti and Roberto Baggio of DAX :)

  • Ian Ross (Aug 20, 2020)

    Excellent. I learnt a lot on first view but I suspect I could watch these videos two or three times and pick up something else each time.

  • Stefaan Louette (Aug 17, 2020)

    Clear and professional training. Thanks for the insights. Ready to take on the other courses.
