Optimizing DAX Video Course
This is the video course version of the Optimizing DAX workshop. It teaches you how to optimize queries and measures in DAX.
DAX is the native language of Power Pivot for Excel, Power BI Desktop and SSAS Tabular models in Microsoft SQL Server Analysis Services. This video course is aimed at users of Power BI, Power Pivot, and at Analysis Services developers who already know the DAX language and want to learn how to optimize DAX formulas and models for improving performance.
The goal of the video course is to enable you to find bottlenecks in DAX calculations using tools such as Profiler and DAX Studio, providing the knowledge to improve the performance by using different DAX formulas or by changing the data model, when required. The video course is made up of over 10 hours of lectures, plus another estimated 8 hours of individual exercises. You can watch the videos at anytime and the system will keep track of your progress. Within the video course you can download the material for all the exercises.
Students have access to a private discussion area where they can interact with the instructors asking questions related to the lectures and the exercises.
Prerequisite: Attendees need a good knowledge of the DAX Language, and a previous experience using either Power Pivot for Excel, or Power BI Desktop, or Analysis Services Tabular. You may acquire this knowledge by following the Mastering DAX Workshop, or by having equivalent real-world experience.

I guess I'll continue buying your courses even I'll stop using Power BI.

Hi Alberto, Hi Marco That was very interesting course. I learned a lot. Thanks to that I have now completely different view on DAX and opimization process. Thanks!

This is a great course. Thanks!

it is fine, sometimes difficult to follow , some videos look outdated, so it would be wort adding annotation or comments on outdated parts below video with the latest info or link to articles with new content. Also it is now not really needed to comment /show what used to be before 2016 or even 2014 and how things were being solved in the past anymore... The Optimizing DAX Exercises.pdf is little bit confusing and difficult to follow in relation to what is shown in the Solution videos (mainly LAB 4 Solutions chapter) , looks like some solutions were not part of the video?
- – Thank you Marian for your valuable feedback. As a matter of fact Marco and Alberto are currently tackling exactly that, a new updated version of Optimizing DAX. Current students of Optimizing DAX at the time of that release will be upgraded to the new and improved version of the video course!
Stay tuned,
Claire

The course is useful, but it seems a bit out of date now and the presentation could be better. The free Power BI Tools course is excellent and seems more recent. I find the presentation difficult to watch. The English skills could be better for teaching a complex subject like this; it pushes unnecessary workload onto the listener trying to figure out what exactly they mean and this distracts from understanding the subject matter. The big screen is a big mistake - the presenter stands in front of the screen and blocks the view; the screen wastes valuable space. Presenters on edX, Coursera, and YouTube manage to avoid this mistake. The sound quality has an echo. They are also talking in very loud voices as though they have a large audience. In the Power BI Tools course, they present individually and the overall presentation is much better. More use of good diagrams would help to explain conceptual information -- they rely too much on words and bullet point PowerPoint slides.

Not related to Review: I like to use the yellow color pen when reading along with your commentary: Is it possible to have other color options as well? e.g orange, and green?? Also I notice that when I print off the commentary - even though I am using color setting - I am unable to print the color highlights that I make . It would be useful to allow color printing to the allow that highlighted sections to print. Related to REVIEW: Very detailed and has complex information that needs time to be digested. I will go through this course many more times in order to be comfortable with it.

For a long time, I doubted whether I needed this course or not. In the end, I decided to go through it and did not regret it for a single second! I feel that after completing the course, I have moved to a new level in my understanding of DAX.

That was great, really enjoyed the challenges set in the labs. This has been a fantastic rebalance of my DAX. Correcting some of the "lazy" that have no doubt crept in while also firming up the reasoning behind some of the things I do "just because" now.

Great course. I'd read a lot of articles on optimization, but this course walks you through a process for optimizing and shows great solutions. The important part is it teaches you how to think about optimizing DAX code.

A fabulous training course that I will start using immediately and that I will have to review a few times to be able to use all of the value provided! I absolutely recommend it.

SQLBI has done it again! Very thorough and very well explained. This is a great supplement to Mastering DAX and is essential for writing fast DAX code. DAX (or at least Power Pivot in Excel) is a bit sensitive; it doesn't take much for DAX code to run slowly and have you wondering how to make it faster.
