Course Description

Demystifying DAX Online is a structured training course that will help you enhance your data modeling and DAX skills using Power BI to produce highly performant reports. (The skills also apply to Power Pivot and SSAS Tabular.)

It’s one thing to know how to write a DAX formula. It’s a completely different level of competency to understand how to write the efficient and effective DAX formula, and understand why it works. This course addresses this, so you understand what is happening under the hood.

This advanced course is created and delivered by world-renowned DAX expert, author of the best-selling book Supercharge Power BI, Matt Allington. It consists of:

  • Video-based training content with examples, demos, and practice exercises that will teach you the more complex DAX topics.
  • Access to our private Discussion Forum, where you can ask questions on how to apply the techniques to your own work. The forum is monitored by Matt Allington, answering any questions about the course content. This forum is also intended to act as a place for students to practice their own learnings by helping others with those questions.

How it Works?

Demystifying DAX Online is a self-paced course, and you can watch the on-demand videos as many times as you like to master the techniques. Upon registration, you will receive access to the online videosdownloadable course materials, and Discussions Forum

As you work through the course, you will be:

  • Viewing the on-demand videos at your preferred time to learn the course content.
  • Completing any practice exercises for the session (typically less than 30 mins). Doing this gives you hands-on experience to cement your learning.

Total hours: 10.5 hours, including watching the videos and practicing with the example files.

Who this course is for?

  • Anyone with a base understanding in writing DAX and who has a minimum of 6 months’ practical experience.
  • Those who are looking to build their skills for career advancement using Power BI as their tool of choice.
  • Those who prefer the structure of guided learning to help steer them along a learning path.
  • Anyone that intuitively realises that they actually don’t understand how to get the result they need from DAX.

Excellent instruction by Matt. He's really easy to follow, and has a very good methodology to learning the Demystifying DAX course. DAX Studio looks to be a very good tool to enable 'visualizing' a virtual table, as I've found one of the most difficult things to do is 'picture' what the resultant table of records looks like, after applying a DAX formula within a visual. Matt is an excellent instructor, as his approach to teaching asks us to thoroughly understand and breakdown a problem we're trying to solve with data modeling.

I think Matt is just really good at breaking down concepts in an easy-to-follow way. He always has good examples and insights and really walks you through complicated stuff, but you are not lost. I thought it was fantastic, especially how he included DAX Studio in the mix.

Even though the concepts can be challenging to understand, Matt gets them across, “Eating the elephant one bite at a time” through explanations, comparisons, and demonstrations. Some of the videos are long and the subject matter can be quite complex. Breaking some of these down into smaller bites would be nice. Thanks for your hard work in putting this together.

This is THE Course one should take if not a complete beginner anymore. I really liked the structure of the course and how it started, revisiting DAX Basics, and then, moving through different topics so that one can get a better understanding on how and why DAX works as it does. Matt’s teaching experience is fantastic and a lot of the concepts you’ve heard about (or not yet) are detailed in the course in a manner that ANYONE can understand them clearly and leverage them in the day-to-day work with Power BI. I totally recommend the course to anyone with some DAX experience.

I loved the systematic explanation of the fundamental concepts of the DAX language with such a simple and easy to understand language without any jargons. However, I think it will be helpful if the length of the videos can be under 10 minutes.

I liked that the course was spread out over a couple of weeks, allowing time to absorb the information. I liked that Matt provided Q&A session and homework activities to complete between sessions. I also liked that the course was somewhat self paced. More interactive learning and longer Q&A sessions with more of a lecture/activity style to walk through problems with Matt may have helped a bit with the learning process.

Key concepts and principals were provided/explained that are hard to find elsewhere. I liked that you are shown the tools to use to develop / debug / improve measures and model, and shown how to move through the complex measure development step by step. Thanks Matt, I really enjoyed attending another course with you.

I love that Matt doesn't just "give" the solution but takes the time to show how to think through the problem and arrive at a solution. I also like that I can retake within the next year as a family emergency prevented me from working through the course the way I would have liked. Great job! Thank you! I've BEGGED my business unit to take this training.

I liked the simplicity with which Matt discussed the concepts and also showing how not to do the calculations. This was really worth it. I have been using Power BI for over 5 years and self-taught. This was my first structured course on anything related to Power BI. The pace, the content, and the approach really worked for me.

Could not speak more highly of Matt or the course. Exceptional and practical content and with a clear pathway from building strong foundation knowledge and leveraging that knowledge into a powerful understanding of DAX & the data model. The level of knowledge I gained on the critical parts of the DAX and context was exactly what I was after. Can’t wait for the next semester to continue to build on what I have learnt.

This course is great if you have had a bit of experience in DAX but are still struggling with some concepts or trying to figure out why the numbers you are getting in a matrix don't look right. It really helped me better understand row context, filter context, and the difference between SUM and SUMX. There are also great tips on writing more efficient DAX code and troubleshooting Measures that are taking a long time to process. Highly recommend this course if you've been writing DAX for about 6-12 months already.

I'm so glad I took this course. There is so much free content on Power BI but this course actually delivers on its promises in a clear and concise way. It is worth every penny. Matt has great knowledge and experience but it is his skill as a trainer that makes this course stand out. Difficult concepts are explained and demonstrated in a way that shows an understanding of the common problems encountered by so many Power BI users. I'm actually looking forward to writing some DAX today!

I found this course to be delivered very clearly and concisely on topics that I didn't even realise were as confused in my head as they were. Matt takes you on the journey with the easy to follow method of teaching he seems to have. I love the online format followed by the Q&A sessions as you can make sure you fit this blocks of learnings around your schedule. Pause, go back and to then have 12 months to revisit again after more practice. I'm addicted to Power BI learning thanks to these courses.

Of all the Online courses I've done this is by far THE best!! Matt is engaging to watch and knows how to teach complicated concepts in a way that makes complete sense. I feel that this is the perfect course for those that are struggling to get over the: "what am I doing in DAX" hurdle. I've done many courses on DAX, but it was never explained to me why something works and why it doesn't. I also learnt interesting new concepts that I never knew existed. Matt has been invaluable in my journey on becoming the analyst I want to be. Thank you so very much!

FAQs

I’m a beginner, is this course suitable to me?

No, this course is for those who have a minimum of 6 months' work experience with DAX. If you are a beginner, you should enroll in our "Supercharge Power BI Online" course to start your formal DAX Journey.

Why is this course a subscription?

Building skill is normally not a "learn today, I'm an expert tomorrow" process. One of the key features of this course is the ongoing access to the online content as long as the subscription is active (initially for one year, and can be renewed annually at a nominal price).

If I get distracted, can I come back and do it later?

Definitely. Your subscription gives you access to the online course videos, sample files, and practice exercises, so you can watch the videos and do the practice as soon as you free up your time. You can get answers to your questions from the trainer via the ongoing access to the discussion forum.

How do I access the course materials? Are they downloadable?

The pre-recorded videos are streamed on-demand and may be watched as often as you like, however they are not downloadable for copyright control reasons. The example files and handouts for each lesson are downloadable.

Where are the pre-recorded course videos hosted?

All the videos for the course are hosted on Vimeo. Please note that some networks and countries block access to Vimeo, in which case the videos will not be watchable. You may want to double-check that you can access Vimeo before registering in the course to ensure that you will be able to see the videos. The easiest way to do this is to try to watch the first introductory lesson for this course, which is free. If that works, you will be fine. If it doesn't work at the office, you could try from your home.

How do I receive my Certificate of Completion?

After all the modules and lessons have been completed, you will be able to download the certificate of completion from the My Courses area of your Account Dashboard. Make sure you mark off each lesson and module as you go through the content in order to access the certificate.
