This is an introductory video course about the DAX language. DAX is the native language of Power BI, Power Pivot for Excel, and SSAS Tabular models in Microsoft SQL Server Analysis Services. The training is aimed at users of Power BI, Power Pivot for Excel, and at Analysis Services developers that want to move the first steps with DAX.
The goal is to teach the DAX language using Power BI for all the examples. You can download the initial Power BI Desktop file used in the demos and repeat all the steps shown in the videos. The same concepts can be used also on Power Pivot and on Analysis Services Tabular. The course is made of 150 minutes of lectures. You can watch the videos at anytime and the system will keep track of your advances. Within the course you can download the slides and the initial Power BI file used in the demos.

Really helpful introduction. This sort of input is really needed in order to avoid frustration and poor understanding. Thank you.

Great use of screen with instructor. Much more like watching a real class than just watching a screen. Especially with the Italian hand gestures!

An excellent way to jump start into DAX as well as being valuable to to those like me who have been doing it a while but are always trying to fill in the gap, returning to the basics when you know more etc.. Definitely one that will be watched more than once though as DAX is not an easy language to get your head around at first. I enjoyed the banter too. My only suggestion is; which might be a bit cheeky because its free, is to have a short assessment in the end, to identify what learnings you need to focus on.

It is not easy to add video content - the studio recording requires a certain amount of planning and preparation. Do you think that a written guide could be useful?

It's a wonderful learning journey to DAX. I watched the lecture of context transition repeatedly to gain a better understanding. It's worthy to spend the time on it.

Excelent , very detailed and specially useful for excel pros that have little experience with database concepts (normalization,modeling, querying, etc.,)

Really good one; especially the practical usage cases

Great introduction to DAX. Even with a few DAX books on my shelf, this video course clearly outlined the essential concepts necessary to start coding with many of the basic functions. By the end of the course, I could author formulas needed to generate key BI calculations in a tabular model--including functions like CALCULATE, FILTER and Time Intelligence. This course was well worth the investment. Highly recommended for beginners and those needing a firm DAX foundation.

Great help in starting to use this easy to understand language.

Thanks so much.It was so useful!

Like the 2 Masters of DAX always say, you have to learn first the theory. This tutorial in combination with the DAX Guide is a very good start. Slowly some code make finaly sense. Truly a very good way to approach into the BI world.
