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.

    Thank you! Excellent!

  • John Mathews (Apr 4, 2019)

    Excellent course and presentation, especially with the (deliberate) mistakes and interactions. The row explosion implications of (S/F)CD-Type2 were eye opening. Would like to see some of the scalability modelling issues discussed such amount splitting by order of magnitude, albeit you did mention date/time splitting, and how patterns change to deal with it. Now it's time to rip up my model and do it properly!

  • Donald Wiesmann (Apr 4, 2019)

    Thank you very much, very good in depth explanations, shows in a detailed way philosophy and specialities for data modeling with DAX in Power BI with still following the Kimball method.

  • Steven Fortier (Mar 17, 2019)

    Wow, this course was so amazing. Marco and Alberto are really good teachers and I recommand taking this course together with the other other one Mastering Dax. The only complain I might have is there's no chapter on handeling different langage in reports. Like if I want to show a reports to my customer in Europe and he talk spanish and the othe one wants it in French. I know there isn't a proper way to do it in Power BI but maybe talk about different possibilities and what are the possible solutions. Except that, everything is well covered. Thank you!

    • That is not a limitation of Power BI and the Tabular modeling where we do not have a good solution yet. The Tabular model supports translations of metadata only, but there are not good solutions for translating entity names (e.g. product names) or report labels. You can figure out workarounds, but any solution has implementation and execution costs - so a feature in Power BI to manage those scenario is really required.

    Great course, I really enjoyed it! I'll continue with the DAX advanced course! Regards!

  • Eva Vackova (Feb 5, 2019)

    Thanks Marko & Alberto for organizing the course. Best practices and scenarios solved during the course are often daily on tables of the data analysts. I enjoyed the course a lot and still need to go back tor review some more complex scenarios :)

  • Yusuf Hamzah (Dec 23, 2018)

    Outstanding materials. The contents are "meaty" and of high-quality.

  • Enrico Vezzalini (Aug 20, 2018)

    congratulazioni, il corso è molto ben fatto ed efficace! Se posso, vorrei aggiungere 2 suggerimenti: - sarebbe utile pensare ad un nuovo modulo orientato alla gestione e controllo dei modelli e del flusso dei dati in un'organizzazione complessa in relazione ai vari modelli di deployment - sarebbe molto interessante apprendere quali soluzioni si possano sviluppare mediante il data modeling per facilitare l'applicazione di tutti i requisiti di privacy by design e di compliance control nella creazione di una piattaforma di BI aziendale (sempre in relazione ai modelli di deployment di cui sopra ed all'utilizzo o meno dei filtri di confidenzialità di Power BI)

  • Maria Luz Munoz (Aug 8, 2018)

    It gave me the confirmation of thoughts and also gave me new ideas. I thank you for publishing this good course.

  • Bill Brown (Jul 27, 2018)

    Now have a much better understanding of data modeling.

  • Emmanuel Dubosson (Jul 13, 2018)

    after using Power Pivot for some years, I could with this course improve my data modeling skills to the next level. The core principles explained in the sections are good understable. Some topics have some (DAX) magic in it. I appreciated the ways proposed in many examples to simplify the data model. Doing it right, it's much more easier and performant. Thanks a lot! With this video course, I'm just only missing eating a pizza with Alberto or Marco.

    • Thanks!!

    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.

    Many interesting new insights. Thanks Marco & Alberto!

  • Paulo Rocha (May 7, 2018)

    Wonderful! SQLBI, Marco and Alberto not only are the best in the field, bust also know how to share their knowledge. This approach of focusing in the Data Modeling and making more efficient DAX expressions takes us to a whole new level in Business Intelligence and Big Data. I'm very pleased with the content and the professional way everything was presented. Keep up the excellent work.
