Data modeling is a required skill to get the best 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 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 course is made of more than 10 hours of lectures, and other 8 hours of individual exercises. You can watch the videos at any time and the system will keep track of your advances. Within the course you can download the material for all the exercises.
Students of the video course have access to a private discussion area where they can interact with the instructors asking questions related to the lectures and the exercises.

Great content from basic to advanced concept of data modelling using DAX. Highly recommended for every BI professionals
- MICHEL PLATINI DE ALMEIDA CESAR (Dec 13, 2019)
Perfect methodology and didactics! For sure the best course in the market!
- Ivon Ampuero (Dec 4, 2019)
- Richard Valdez (Nov 18, 2019)
This is a fantastic course!! I am studying this course concurrently with the Mastering DAX course and I am finding it quite useful to go back between both courses. I am eager to continue in this wonderful journey of learning the DAX language and applying it to my work.
- 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.
- Lucas Minikoski (Oct 24, 2019)
Thank's, this course leveled me to another way of "DAXing". Now I feel better when I open the PBI and start measuring. Thank's a lot!!!!
- Abhijith DSouza (Oct 16, 2019)
Thank you Marco and Alberto for a wonderful course. A lot of real world applications were covered in the course and also different techniques to solve them. I particularly enjoyed the techniques which we shouldn't use and the reasons for not using them. Highly recommended for anyone interested in an in depth analysis for Power BI data modeling.
- Claudio Trombini (Oct 14, 2019)
Best course of Data Modeling!!!
- Thomas Allan (Oct 7, 2019)
A thorough review of model scenarios (simple to complex) covering date and time, historical attributes, snapshots, intervals, many-to-many relationships, differing granularities, segmentation, and multiple currencies.
- Luigi Bissolotti (Oct 2, 2019)
lessons and examples are very clear discussion sections are very useful
- Andreas Ratz (Aug 22, 2019)
Again a perfect course. Very useful are the patters provided. So all you have to do is to identify the right pattern and apply ;-)
- Sergio Murru (Aug 15, 2019)
This course covers different scenarios, from the simplest to the most complex ones, using them as examples to give a clear explanation of the different techniques that can be used when building the data models for our reports.
- Ciro Gómez Parssian (Jul 13, 2019)
Excellent and astonishing course.
