Introducing DAX Video Course

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.

    At the end of the part "What is Time Intelligence" you show the below calculation. I would have liked a bit more explanation on how to interpret the two 'Date'[Date]. Otherwise a great course and I look forward to the next. CALCULATE ( SUM ( Sales[SalesAMount] ), FILTER ( ALL ( 'Date' ), 'Date'[Date] <= MAX ( 'Date'[Date] ) ) )

    Great course!

  • Sunny Asigalla (Jan 19, 2024)

    It's an amazing course. I've learnt a lot of new things about DAX about which I wasn't sure before. Especially liked the approach which showed not just what should be done but also what should be avoided, learning from mistakes helps understanding even better. Really amazing. Thank you

    Some excellent explanations and illustrations of the various functions and the syntax within DAX. I am a new and very inexperienced user of DAX and have struggled to understand some of the expressions and the uses of variance functions. I will watched the videos again and apply many of the things learned from the videos in a separate database and then consider whether to but the master or optimising courses - at this stage, I have no understanding of the difference between the courses. In addition, I will decide whether I need to buy a book. Thank you.

    Very comprehensive introduction to using the DAX language in Power BI. The basic concepts are well explained theoretically and their application is clearly shown through examples. Thank you very much!

    Excelente curso uno de los mejores que hice

  • shady salman (Dec 25, 2023)

    It is one of few courses that made me understand the complexity of DAX in simple and plain English. Now I am confident to say I know the basics of DAX.

    Very informative course.

  • Claudinei Taiacolo (Dec 19, 2023)

    Very good content. I will do the master course, soon.

  • Angelica Young (Dec 15, 2023)

    Awesome intro with super personable instructors! Definitely helped me understand quite a few terms I'd heard before but hadn't yet wrapped my head around. Looking forward to the next series!

    Incredibly well put together course. Fantastically presented. Even though it was an "intro" course, I learned a TON about the "why" behind the way things work. Thank you for making this course available!

  • Fergus Weinert (Dec 7, 2023)

    I thoroughly enjoyed this course, and was very helpful in introducing me to the basics of DAX. I enjoyed listening to the two presenters also, as their chemistry helped keep the lectures entertaining.
