Introduction to Data Modeling for Power BI is an introductory video course about data modeling, which is a required skill to get the best out of Power BI, Power Pivot for Excel, and Analysis Services. The training is aimed at users that do not have a background knowledge in data modeling for analytical systems and reporting.
The goal of the course is introduce the primary concepts of dimensional modeling, using practical examples and demos to illustrate how to obtain the desired result without having to write complex DAX expressions. Creating a proper data model simplifies the code to write and improves the performance. The course is made of 100 minutes of lectures. You can watch the videos at any time and the system will keep track of your advances. Within the course you can download the slides and the Power BI files used in the demos.

I recommend, nicely explained introduction to modeling for Power BI. Thank you

Excellent presentation. Thank you so much for sharing knowledge.

The German translation is not very good. Tables is sometimes Tabelle (correct) and very often Tisch (the table you eat on which you eat...). Or sometimes Date is translated as Dattel (something you eat like figs). I hoped to use it for people who don't like to learn stuff in English. Never mind the course is very good as always !
- – Thanks for your feedback - unfortunately, we have to use automatic translation service as reported in the description of the video course: "(*) Translated automatically from the original English captions."
Originally we tried to create manually curated translation, but it was economically unsustainable. We received many requests for translations and the feedback was that an automatic translation is better than no translation, so we went for it - although it is not ideal and far from our standards.

I love your videos! You make everything simple to understand. The process is always building from one scenario to the next in a way that makes the entire process understandable. Thank you so much for sharing your incredible knowledge with us.

It was an awesome course. Now I understand where I need to start to improve for manage PowerBI and go to the next level. This is the second course that I take and the only thing I can say: you never disapoint me guys. You are awesome.

All the lectures were clarifying, the content and examples matched my expectation. Most of content was a refresh to me, however I found the whole approach very stimulating, so I wish I could purchase deeper courses or books of Russo and Ferrari in close future. I really enjoyed your initiative!
