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.

    A lot of knowledge, but it should be more emphasized that the course is created for advanced DAX users, not the ones who would like to start the journey with data modeling.

    • Hi Julia, Thank you for your feedback. We do offer the free video course, "Introduction to Data Modeling" which you may find helpful prior to learning the "Data Modeling for Power BI" video course. Claire

    Great course. Lots of good information. Thanks guys

  • Erick Munoz (Jun 4, 2021)

    Hey guys, I like the course, but I feel letdown. I'm not exactly a newbie but there are a lot of technicalities I wish were explained at some point or at least referred. I get that this is not a DAX course (I have already bought other courses in order to grasp more) but things like filter context, ambiguity, Iterations, explanation of Calculate(values[]) and other hardcore combinations of dax are barely touched and regularly used. I have found some answers on your own Youtube account and that's seems to indicate that you are aware of this gap between what people like me (basic users) are trying to grasp. Basically I'm giving you the benefit-of-the-doubt rating that everything will come together with your other courses.

    Great course! It's good to have this reference to come back while getting field experience.

  • 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.

  • Vyacheslav Ilnytskyy (Aug 8, 2020)

    Great course. I really enjoyed it and found plenty of things to implement or change for my situations. But I think this course as well as book (it's great that you can do both book and course in parallel) are missing the particular solutions. Meaning, it would make much more sense to include the M reference the same way it is done for the DAX course and The Definitive Guide to DAX book. Because as it is said many times in the course "Here is a DAX code, but it's the worst option - better use M or source". But there is no M in this book... This is also the reason, why I've stopped doing labs after 5th task - I don't know functions. I can't solve Labs without copying result from the Solution. And it doesn't make any sense to do it that way. So, I decided to come back to them after DAX course. Anyway, I think the best would either to add M reference, or add separate M course. Otherwise, thank you for this wonderful course. It definitely worth its money.

    • You made very good points, thanks for the feedback. The goal of the Data Modeling class is to make people aware of the data modeling requirements. However, there are many ways to transform the data: - Using SQL - Using specific ETL software (SSIS, Azure Data Factory, Informatica, ...) - Using Power Query - Asking for specific datasets to the IT Many Power BI users fall in the last bucket: they can spend time learning and using Power Query (which required a completely separate course, which we do not have), but we also have seen that many users can simply forward the requirements to their IT once they understand what to ask. For this reason, we designed the training in order to provide the information required to understand what is the proper data model required to solve a business problem. This particular topic is not covered in training about specific tools to transform data, and it is the real goal of this course. We probably have to better clarify this goal in the course description to set the right expectations. Thanks again for your useful feedback!

    Very well done video course. I found it particularly useful in understanding the errors I can incur in when building my data model and how to structure it in a proper way. Some of the subtitles are wrong, maybe to be reviewed.

  • Robin Neven (Oct 25, 2019)

    Very good: clear explanations and examples, though harder than I had expected. But that's good because it means there was a lot to learn! Minor point of improvement: sometimes the assignments weren't totally clear to me. In those cases it started with a description, but never really asked a question/gave an assignment.

  • Bill Brown (Jul 27, 2018)

    Now have a much better understanding of data modeling.

  • Eduardo Rocha Clemente (Jun 24, 2018)

    The last Module that I really have done the exercises was the "Analyzing date and time intervals". I think that the previous course that you advised me to do "Introducing Dax", the free one, was not enough to understand the solution that was depeloped in DAX code. I intend to do the "Mastering Dax" course, and do all the exercises again in this course to a better understanding . I feel that a roadmap to master DAX is needed

    • Thanks for the feedback! Please, keep in mind that the goal of the Data Modeling for Power BI course is to teach how to set the goal in designing the data model, not in implementing the transformation. The way you have to consider the exercise is in practicing the definition of the data model. It would be better to use SQL or Power Query (M) to obtain such a result. For practical reasons, we used DAX to accelerate the creation of the required table, otherwise the course would have dedicated 70% of the time describing how to use SQL and/or Power Query, with a more complex setup for the exercises required.
