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.

    I liked it, very clear explanation and demos. Thanks for making this video..

  • Karin Rehers (Jun 18, 2018)

    Erst hatte ich Bedenken, ob ich dem englischen Vortrag werde folgen können. Das ging erstaunlich gut, und wenn es mal hakte, konnte ich den Teil ja mehrfach ansehen. Danke, jetzt habe ich endlich die Dax-Grundlagen verstanden.

  • Rachel Hill (Jun 14, 2018)

    Excellent, really well explained

  • Romeu Wolfgramm (Jun 8, 2018)

    would be possible to enable the legen in the videos? to the Portuguese for example ;-)

    • Romeu, currently the subtitles are available in English and Spanish. You can enable them clicking on the CC icon in the lower right corner of the video player. We will consider creating Portuguese subtitles in the future depending on requests. Thanks!

    The video courses are very good and simple to understand !

  • Eduardo Rocha Clemente (Apr 18, 2018)

    As an introduction course is good enough to taste, but it doens't show a kind of roadmap for mastering DAX. Perhaps is a good idea to add this information right in the beginning of the course

  • Bare Udusegbe (Apr 15, 2018)

    Great intro to the "beautiful language" DAX!

  • Alec Guerenstein (Apr 14, 2018)

  • Paulo Alpoim (Feb 9, 2018)

    Great materials.

  • Peter Kötzing (Jan 27, 2018)

    I find this course very useful, and having 2 presenters adds another dimension to it: It's very entertaining too - exactly because there are sometimes 2 voices at the same time. Who cares? I like the vivid Italian style much better than those boring Indian monologues. Just bought the 'mastering' course ...

  • Olga Avtushko (Jan 24, 2018)

    The course is wonderful. Thank you. Clear explanation of the important points, especially for DAX beginners like me.

  • Abdelkader Gharbi (Jan 22, 2018)

    I think , without compliment it's great, i think all web site is great and i found lot of things usefull for to fix some issues in my model at work , for this i give five stars. ......and as alberto said "DAX is simple , but it is not easy", it's need time , work and patience.

  • Rajayoganandha Sekaran (Jan 11, 2018)

    This is a great course for equipping oneself with enough tools to work on any data model. Thanks for explaining in great detail about the nuances of various function.

  • Victor Jemio (Jan 11, 2018)

    Great course. Very clear and the lenght of the videos is just perfect.

  • Ana Garcia (Jan 5, 2018)

    I believe it would be better if we could complete some exercises at the same time.

  • Adilson Costa (Jan 5, 2018)

    This is the most interesting free course I am did about one tool! This is an amazing DAX course. You are to be congratulated for this grating job.

  • Bart Titulaer (Jan 2, 2018)

    Thank you very much. I really liked this way of presenting. Also compliments for your assistant who asked very good questions in between and also gave some good intermediate remarks. Good team!!

  • Wyn Hopkins (Jan 2, 2018)

    Very usefull.

  • Alex Powers (Dec 28, 2017)

    As a proud owner of The Definitive Guide to DAX this series was a fantastic complement to the book. To be honest I can not believe the amount and wealth of content that was given away for free in the course. I'm excited to look into the other courses as I continue on my DAX journey.

  • Sanjeev Soni (Dec 25, 2017)

    Excellent no words of thanks touched all the key aspects of DAX

  • Natarajan Ganapathi (Dec 22, 2017)

    It will be unfair, if I give anything below a 5*.

  • Andrés Lagerlöf (Dec 20, 2017)

    Great course! Thank you!!!

  • minshen liang (Dec 20, 2017)

    Good!

    Thank you Marco and Alberto! Your course helped me see how wrong is the "Excel table mentality" when working in DAX.

  • Richard Martinez (Oct 17, 2017)

    Great course. I highly recommend starting out with DAX to take this course.

  • Dave Shepherd (Oct 6, 2017)

    Great! Helped explain early chapters of your book. Reading can get a bit tiring, so nice to sit back and watch and listen. Thanks!

  • Sujata Mehta (Oct 6, 2017)

    It is said that it is the mark of a genius to explain complex concepts in a simple manner. Thank you Alberto and Mark, you are geniuses!

  • Giedrius Vegys (Oct 5, 2017)

    This is great course. One thing I am still missing - does CALCULATE add row context to existing filter or completely change existing filter?

  • Wynand Coetzee (Oct 5, 2017)

    Nice intro into DAX , thanks guys. Sometimes I still want to write DAX like I do TSQL..so it is a mind set change that I am learning and enjoying.

  • Shannon GILL (Sep 27, 2017)

    Great course. I will refer back over and over again. My only suggestion is to add a transcript so I can easily refer back to a certain section.

  • Puneet Dobriyal (Sep 26, 2017)

    Very nice explanation and course outline.!!

  • Elbina Rizakhanova (Sep 23, 2017)

    Very, very good! Many thanks! I after this course I'll definitely apply Mastering DAX course

  • Elbina Rizakhanova (Sep 23, 2017)

    Excellent! Many Thanks! After this course I'm sure that I apply to Mastering DAX workshop course!

  • Jayson Chabot (Sep 23, 2017)

    Wow, I didn't expect an introduction course to teach me about the iterator functions ...what an amazing tool to replace my reliance on calculated columns! I would have awarded five (5) stars if there was a bit more story telling ...it would be nice to have a few laughs from your many years of experience teaching DAX.

  • Anton Kwang (Sep 22, 2017)

    Excellent & Informative

  • kalina ligmanowska (Sep 21, 2017)

    Thank you guys, that has been extremely helpful :)

  • Mikkel Nissen (Sep 20, 2017)

    To fast pace, specially the "not visible" guy running the demo in PowerBI - some extent annoying to hear the two discuss typos etc. Otherwise fine for a free course.

  • Michael Dillon (Sep 14, 2017)

    Fantastic! Thank-you Macro and Alberto. Excellent compliment to the Book. Michael Dillon Community College of Batimore County

  • Robert Jansen (Jul 13, 2017)

    Great! I think for beginners it is still a lot to understand. Only with a lot of practice you can master it.

  • David Linnemann (Jul 12, 2017)

    This was a great intro to give you an understanding if the Mastering DAX course is for you.

    great course.

  • Michael Woodman (Jun 23, 2017)

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

  • Donald Parish (Jun 22, 2017)

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

  • Vanessa van Gelder (Jun 20, 2017)

    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.

    • Hi Vanessa, thanks for the feedback! 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?

  • Julian Chen (Jun 18, 2017)

    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.

  • Hong Nguyen (Jun 17, 2017)

    Great

  • Oscar Zapata (Jun 16, 2017)

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

  • Sobieslaw Kulej (Jun 15, 2017)

    Really good one; especially the practical usage cases

  • Mario Anzaldua (Jun 13, 2017)

    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.

  • Angela Dimmick (Jun 12, 2017)

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

  • orxanbabashov (Jun 12, 2017)

    Thanks so much.It was so useful!

  • Arkadius Bombka (Jun 10, 2017)

    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.

  • Viorel Ca (Jun 10, 2017)

    Outstanding presentation. A lot of complex concepts explained very simply. Very useful! Thanks a lot! Viorel

  • Elena Shuvalova (Jun 9, 2017)

    Great course! Thank you!

  • Andras Ujszaszy (Jun 7, 2017)

    Was a great course. Thank you.

  • Yoshi Deguchi (Jun 6, 2017)

    Why you guys are arguing? Hard to follow the course.

    • Yoshi, can you explain what you mean with your question? Is it something related to specific part of the training, or is it a general comment? If you can provide some more detail, it could help us understanding the issue and improving the course. Thanks!
