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.

  • Robert Williams (Oct 4, 2019)

    Thank you so much for the course, it was great to work through and really helped me get an introduction to DAX and give me the foundation and confidence I need to move forwards and not get lost in starting out to learn the language. I would love to have seen something that forces more hands-on training, as in some practices + test questions at the end of each module or video. WiseOwl does some nice practices for example (although a bit hidden) perhaps doing this will help build a better foundation before people then move onto the next (paid) courses.

  • Christine Rowe (Oct 2, 2019)

    This course is just what I was looking for! There's lots of how to videos, but they don't explain the concepts or help to create a foundation from which I could build and grow. This course has filled many gaps I didn't even know I had in my foundational knowledge. Thank you!!

  • Markku Kolehmainen (Oct 1, 2019)

    Just great! Presentation was really clear and easy to follow. Content was also sufficient.

  • Michal Suplinčák (Sep 27, 2019)

    I think, It was perfect introduction to this language. I will recommend to my colleagues and friends. Only one thing, your font does not support letters from my native language.

  • PABLO MORICZ DE TECSO (Sep 27, 2019)

    It's a really good introductory course for people like me who know nothing about DAX and want to start learning about it. Still, as a suggestion I would recommend checking for mistakes while explaining during the videos which can confuse the audience. In general you after correct yourselves, but that leads to confusion sometimes. Also, in some videos you both speak at the same time, making it complicated for the viewer to understand what's happening. I hope this can be corrected in future versions of the introductory course for future viewers to make the most of this amazing course.

  • Alessandro Farolfi (Sep 24, 2019)

    GREAT!!! Thanks a lot!

  • Luis Angel Mezones Maldonado (Sep 22, 2019)

    Great courses! Very enjoyed learning so mouch think about DAX in so few videos. Thank you very much

  • Trudy Mendis (Sep 20, 2019)

    I loved the training, it has given me answers to some of the problems I have been encountering, and more that I can do with my data.

  • jhampier tapia (Sep 19, 2019)


  • Kim Beck (Sep 17, 2019)

    Very good getting started review. Just wish that would be some "workshop" included in order to get some hands on with the basics and this help remember better.

    • Thanks for the feedback! The Mastering DAX video course has more than 70 exercises that requires at least 10 hours to be completed - take a look at that!

  • Madelyn Dedal (Sep 7, 2019)

    This is very helpful free course for someone like me who is just a beginner in using the Power BI Tool in our organization. It is pretty cool how the DAX perform behind the data visualization. Great speakers as well. I hope you could include me in all other free courses that you offer as I am really happy to learn more. Thank you!

  • Bryan legge (Sep 6, 2019)

    It took a bit to get use to the accent, but strangely enough it grew on me. I enjoyed the examples and the back and forth comentary.

    Very helpful course and I intend to go back and review some parts of the course wherever I have a question.

  • Leonardo Nunes Couto (Sep 3, 2019)

    Very good training. Instructor knows in deep about the proposed subject. He presents it in a pretty simple language making it very clear even for for beginners. Other DAX training videos I watched on Internet were so superficial and the presenters seems to be reading a teleprompter. Completely different from this one. Very good job, Alberto.

  • Mark Fillingham (Sep 3, 2019)

    Just enough detail explained brilliantly!!

  • Malgorzata Poniatowska (Aug 30, 2019)

  • Placide Roy (Aug 30, 2019)

    Thank you so much. This course is very clear, very complete (although only an introduction to the topic), very smart in the way the concepts are exposed. For sure, I will come back on the whole presentation that I discovered today since it was so rich and consistent _ before steping to a next course. Thanks again, for offering the quality and consistency of information that one expects when registering to a course. Regards.

    This is a great course for starting to learn DAX. Thank you!

  • Nick Poulis (Aug 4, 2019)

    A really good course. It helps a lot clarifying some dark corners of how DAX works and a better undersanding of the contexts. It already helped me in a few cases to optimise my reports without having to do tricks in my SQL Views. I'm proceeding to Mastering DAX course. Thank you.

  • john keegan (Aug 1, 2019)

    Really great breadth and depth of material. I have reviewed the course several times over the years. It helps reinforce lessons that you need over your entire Power BI journey.

  • Paul Ramírez (Jul 2, 2019)

    Top quality course, amazing for the price of $0! Clear and concise explanations that focus on the key aspects of writing efficient and effective DAX code.

  • Shawn Gallagher (Jun 26, 2019)

    Solid intro, thanks! I noticed one lecture maintenance issue. Note that the Power BI team is apparently listening; no longer is "Cross filter direction" defaulting to "Both", but rather "Single". I am using the June 2019 Power BI update. Edit relationship | Cross filter direction | Single {default}

  • Helmar Träger (Jun 25, 2019)

    Really good video course

  • carry Zhou (Jun 23, 2019)

    The course is pretty good for providing the basic idea of DAX

  • Steele Carr (Jun 21, 2019)

    Excellent. Especially for a free course. Its not designed to give you everything you need but gives you a very good understanding. Only negative thing to talk about is the way they jump around sometimes during the explanations.

  • Isabelle Palaster (Jun 18, 2019)

    I really enjoyed this course and got a lot out of it. Thank you

  • James Ulatowski (Jun 14, 2019)

    Strong course for an introduction. Leaves one very interested in further study and intent to use the newly acquired knowledge in BI tasks at hand. The presenters are clearly expert in these topics and it was both very informative and intellectually satisfying to watch and listen to them. The chats between them are typical of the dialog of smart people at work, no need to say excuse me and thank you - that is a given and wastes time.

  • Daniel Melo (Jun 14, 2019)

  • Pablo J Moreno (May 27, 2019)

    This is the best DAX course that I ever had. Alberto Ferrari and Marco Russo are the real DAX masters and they know how to teach. Thank you

  • Luca Argentiero (May 25, 2019)

    Great Course and well done. Sometimes a bit fast but you can always pause and try out if you understood the topics. Thanks for putting the course out !!

  • Branislav Klimo (May 22, 2019)

    One of the best courses on DAX out there - easy to follow and very practical. Good job!

  • Mathew Westwood (May 22, 2019)

    This was a very good free intro to DAX course, I was however I did have issues with the comments sections, the comments not loading or loading very slowly

    • We use DISQUS to manage comments. We noticed that it is slow on Microsoft Edge but it works much better on Chrome and the new Edge version based on Chromium (not released yet). Which browser version are you using?

  • Sani Garba (May 21, 2019)

    Dax is more than a functional language, it is a gateway to endless possibilities. I am privileged and opportune to learn from the Dexterous Masters of Dax

  • Mario carvajal (May 20, 2019)

    Excellent presentation!

  • Christopher Jones (May 19, 2019)

    Very good. About the only thing I would've like to have also seen is consideration of query performance. Example: There was discussion of RELATEDTABLE and also of CALCULATE. If one is creating a calculated column in the Customer table for TotalSales, there is the option of basing the calculation on either function. Would be nice to know the performance implications of the choice. But maybe that's for the Mastering class.

    • There is a specific course for this: Optimizing DAX! However, RELATEDTABLE and CALCULATE have the same behavior because RELATEDTABLE is just an alias for CALCULATETABLE. Performance is the same.

    Great Course!

  • Janet Grant (May 9, 2019)

    I'm not new to data manipulation, having spent many years with Excel (prior to Power Pivot) and SQL, and I enjoy teaching myself new software by jumping in and making things. But I was totally new to DAX and Power BI, and I was struggling even with the most basic calculations - getting correct answers just by trial and error. This course was exactly what I needed to get a running start on making my own data models and visualizations! If you're not familiar with databases, relationships, and data queries, you might be a little lost. But with a basic background, these guys walk you through the logic of DAX in a very common sense kind of way. I found myself constantly thinking, "Ohhhh!!! *That's* how that works! Now it makes sense!" Thanks Alberto and Marco!

  • Laura Arlandis (May 8, 2019)

    Great introductory course for the DAX language

  • Derrick Dugas (May 7, 2019)

    Very informative. I have some Power BI hours under my belt, so the speed of the video lectures was not much of an issue for me, however, for those who have less experience, I can imagine them having to watch certain lectures multiple times, or at a minimum, pause and start again, which might discourage some individuals from completing the course.

  • Vivek Rawat (May 5, 2019)

    Concepts are explain technically and how they behave, how using different things for example sumx or calculate can result into similar calculation, these things are really useful to know. In addition to this, I believe putting a use case or scenario showing when one will use one technique against other will of great use. I am learning all behavior of different technique but there is only question in my mind why i am learning different ways of calculating same things, only if there are examples which showing when one thing will be use against other will be of great use. I am happy discuss things in more details.

    • This is an introductory course which goal is to introduce the basic concepts of the DAX language. A more complete course is the Mastering DAX, which has the same approach going deeper in each topic. If you are more interested in learning practical solutions to common patterns, we have DAX Patterns, where you can find many practical examples without the explanation of how DAX works behind.

    Very useful information for beginners, this course is unique because it highlights with due focus some of the most important information in all of DAX, specifically regarding evaluation contexts.

  • John Nickell (Apr 26, 2019)

    Very good! I've been stumbling around in Dax/PowerBI and watching this course explained some of the rules behind things that I had inferred. Understanding the rules (especially filters context and how calculate modifies the context) may have gotten me past the road block I have been beating my head against! Thank you!

  • Deepak Chauhan (Apr 20, 2019)

    Wow!! Is it possible to get the sample dataset used in the exercises? So we can practise side by side on each topic.

    • There is an initial section where you can download the file used for the examples. This course does not have exercises, they are included in the full Mastering DAX video course.

  • Jimmy Tuck (Apr 19, 2019)

    This is an excellent primer for the Mastering Dax course. Also, the ability to use Dax within PowerBI opens a vast array of tools for the data analyst. Understanding evaluation contexts is key to unlocking the power of PowerBI.

  • Carlos Castro (Apr 18, 2019)

    Excellent course. Baby step video to learn DAX. After months of completed, time on time I come over when I want to refresh knowledge and solve issues on my models/report. Marco and Alberto are highly professional and "maestros.

  • Bagus Deddy andri Suharto (Apr 18, 2019)

    very good

  • ERIC SCOPINHO (Apr 18, 2019)

    Amazing course. Very clear and concise but at the same time covered a lot for an introductory course. The visual aids and instructor are great! By far, the best DAX intro I've seen online.

  • Mark Beedle (Apr 15, 2019)

    This was a wonderful introduction to DAX. I found it very helpful how the course builds on itself, starting from basic concepts and then adding more complexity as the course moved forward! I recommend this to anyone who is thinking about tinkering around with DAX/PowerBI.

  • Christon Petersen (Apr 14, 2019)

  • Julian Ignacio Yepes Arroyave (Apr 12, 2019)


  • Mourad BENKADOUR (Apr 11, 2019)

    Thank you a lot for this excellent course. it would be better if we can test our dax knowledges by some exercices, quiz, so by that we can decide if we able to upload to next level.

  • James Moore (Apr 7, 2019)

    I can't think of anyone I would rather learn DAX from than from Alberto and Marco. I have read a lot of their articles and seen some of their seminars regarding Power BI and DAX. Also, their books are excellent regarding this subject. This was an introductory course, but I highly recommend it for anyone just starting out with writing DAX code to understand the various filter contexts. Thank you, Alberto and Marco for these free videos starting with introducing Power BI and this introducing DAX course. I plan on moving forward with your more advanced DAX courses soon.

  • William Eunice (Mar 30, 2019)

    Outstanding overview of DAX. It really answered some of my basic misunderstandings. I was relying heavily on the Quick Measures in Power BI but this really gives me a platform to start producing measures that give better insight than can be had out the box. Bravo!

  • Katherine Jewell (Feb 27, 2019)

    This course was extremely beneficial for just getting the concept of DAX before diving in.

  • Peter Vaneff (Feb 26, 2019)

    An excellent course. Finished it in one sitting. I wish there were a quiz/exercise section, though. Interspersed throughout the lectures. For example, right after CALCULATE is introduced, do a bunch of CALCULATE drills. Maybe even you could mix these dills up a bit, i.e. do a drill on CALCULATE a few topics later. Overall, though, an excellent course! And free :). Thank you.

    • Thanks for the feedback! Please note that the Mastering DAX course includes exercises at the end of each module.

    Great course. I've learned a lot. I will come for reviews and with some questions in the discussions.

  • Luigi Neri (Dec 28, 2018)

    I really enjoyed the course. It is really well taught. The thing I liked the most is your approach. Out there you can find many people who can show you how to do things but that do not explain the theory behind. In your course, instead, you go deep showing the theory and try to teach the correct way to think DAX. The part I like the most is that related to table calculation and context. You explain difficult concepts in a good way. I acknowledge that in order to master these concepts, someone needs to spend a lot of time using the language but in your course, you show the way. Thank you very much for making this course free.

  • Irvin Barrera (Dec 27, 2018)

  • Charlie Abramson (Dec 7, 2018)

    Simply excellent. I have some background knowledge from using Excel and Access and wanted to learn Power BI. After learning a bit about Power BI I realised I needed a better understanding of DAX and this course absolutely hit the spot. If I have a need to learn more about DAX, I'll be back to for the Mastering DAX course. Thank you both!

  • Thomas Williams (Dec 7, 2018)

    Great overview of key concepts in DAX.

  • Eugene Nabatov (Dec 6, 2018)

    I feel that the course content is great yet the video can edited and trimmed. Multiple instances of Marco and Alberto not being on the "same page". I hope the pay per view courses are better rehearsed.

  • Cristian Anghelache (Sep 14, 2018)

    Excellent presentation, what I liked the most were the explanations regarding the way the functions work, what is actually happening in the background, understanding how the functions actually work not just what they do, brought me a high level of awareness and new I can take better use of them. Thank you very much!!!

  • Ernesto Rodriguez (Sep 14, 2018)

    Excellent introduction to the DAX. Alfredo and Marco are masters of the language.

  • Muhammad Nauman (Sep 14, 2018)

    Excellent to have a broad view of the language.

  • Martin Zukovec (Aug 20, 2018)

    Greate guided course. Detailed explanations. I really liked the comments of the guys behind the PC. It's good to have someone who thinks in a way of a listener and not as a lecturer, who has much more experience and sometimes unknowingly misses an important aspect of a function or clicking specific button etc. Best regards

  • Plamen Ivanov (Aug 19, 2018)

    Great course! Started my Power BI journey a months ago and what I really wanted to find is a well-structured lectures, step-by-step training in order to progress with limited waste of time digging into too advanced stuff at the time of learning - sqlbi learning path is all I was looking for! One recommendation - put on a more easily to find place at your site, I don't even remember how I find this link , but I am on it for the next months:) already bought next training (Data modeling) and can't wait for your 2nd edition of DAX book in the beg of Jan.

Some of the slide contents and screen displays weren't fully displayed throughout some of the videos. I was able to obtain the full content by pausing & refreshing. The interaction was very important as it provided perspectives on various ways to do things in DAX.

I like the vivid Italian style much better than those boring Indian monologues. Just bought the 'mastering' course ...

    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)

  • 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 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 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.

  • Émerson Corrêa (Jul 12, 2017)

  • 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)


  • 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!
