Mastering DAX Video Course

This is the video course version of the Mastering DAX workshop.
DAX is the native language of the semantic model in Microsoft Fabric, Power BI, Analysis Services, and Power Pivot for Excel. The training is aimed at users and developers of these products who want to learn and master the DAX language.

The goal of the course is to teach all the features of DAX, providing the knowledge to write formulas for common and advanced business scenarios. The video course consists of 32 hours of lectures, including demo files to reproduce the steps shown in the videos. You can watch the videos at anytime and the system will keep track of your progress. In the course, you can download the materials for all demos and exercises.

Students have access to a private discussion area where they can interact with the instructors and ask questions about the lectures and exercises.

  • Sergio Siffredi (Aug 24, 2020)

    excellent training and awesome trainers

  • Santosh Raghunath (Aug 22, 2020)

    Marco and Alberto are Amazing. Explaining DAX is not easy. Marco and Alberto make it easy for understanding. Exercises provided are super amazing. Makes you think hard and this, in turn, helps you grow. On the other hand, Sergio quickly replies back to your discussions with appropriate answers. By the time we finish the course, we feel like a family. Family of DAX. Thank you.

  • Yael Amitay - Preiss (Aug 19, 2020)

    thanks a lot! it was a great course!

  • Ka Ly (Aug 14, 2020)

    Absolutely wonderful course. Alberto and Marco are Professionals at the highest level with the ability to teach highly complex topics in DAX. I will have to watch this course and review the book several times to get all the knowledge that they are presenting. I highly recommend this course for all Power BI users. Thank you so much for sharing your knowledge!

  • Paolo Rizzo (Aug 13, 2020)

    I am amazed by the amount of work you have put in this video course. Very interesting and didactic. I would have appreciated Power BI demos for the new chapter on calculation groups. In conclusion, you made me realize what I want to work for my future career. Many thanks!

  • Jorge Daniel (Aug 4, 2020)

    Hi Alberto and Marco, Great course. Actually it was much more than I expected and I will surely revisit the content many times.

  • Rodolfo Flores Mendez (Jul 22, 2020)

    I am a business consultant that in the past 2 years transitioned from conventional data analytics tools (a.k.a "excel") to more sophisticated data analytics and data science engines. I had been looking for a long time for a comprehensive course on DAX and PowerBI, that covered enough theory to consider myself a DAX developer, and feel comfortable writing complex code in DAX for more sophisticated business applications. I am very happy to say that THIS IS THE COURSE. It is the perfect balance between a pragmatic and a theoretical approach. It has helped me skill-up to the next level in DAX and I found it to be the best course available in the market. Other training programs are too "generic", they cover only the basics and leave a lot of loopholes. They try to get you something “fast” and “simple” so you can apply PowerBI right away, but such courses don’t make you a DAX expert, just a superficial analyst. This course is the only one that again, really skills you up to the next level to consider yourself a true DAX coder. Cant wait to take the Optimizing DAX course! Congratulations to Alberto and Marco, I am your #1 FAN.

  • David Bianconi (Jul 20, 2020)

    This was the best course I have ever followed and not only with regards to Business Intelligence. Congratulations to all the SQLBI staff

  • Sandeep Singh (Jul 13, 2020)

    I have just completed 50% of the course, and honestly I can understand the mechanics of DAX, this is not an beginner course for sure, but it will take your DAX knowledge to the next level. Can't wait to start on reading the book - 'Definitive Guide to DAX - 2nd Edition' after completing this. I have just a suggestion, if new exercises are added constantly modelled after real life business problems, the course would have warranted 6 stars. But the included examples are tough and in depth to test you knowledge of DAX. Bow down to DAX wizards, Marco Russo and Alberto Ferrari!!

  • Amaru Quinones (Jul 12, 2020)

    Extremely great!!

  • Armando Barajas (Jul 9, 2020)

    Excelent course

  • Ciro Gómez Parssian (Jun 21, 2020)

    Best DAX course, period. The Maestros way of teaching DAX is elegant, sharp, with a deep understanding of use cases and engine logic, and truly business-oriented. In other words: pure Business Intelligence.

  • ELIAS BARBOSA DA SILVA JUNIOR (Jun 14, 2020)

    Very complete course. Covers the many hidden traps in the DAX language.

  • Barnabas Toth (Jun 5, 2020)

    Great course! Nice explanations!

  • Abdelrahman Abdou (May 28, 2020)

    Great course for Learning DAX! A true Gem!
