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.

Overall, this course provides a solid understanding of DAX language including key concepts like Cardinality, Filter Flow, Evaluation Context etc. Having some prior knowledge is useful and recommended.

Throught out most of the lectures, especially Intro to Dax - Measures it really felt like the presenter and the one controlling the screen were not in sync and practiaclly fought with each other. It was quite distracting. In the measures lecture we are told not to include the table name when referring to measures and even in the example they show it doesn't. BUT in my version, presumably newer, it does. Does that mean best practice has changed? I could never get my visualization to look the same in the time intelligence lecture. If I used the matrix, which they did, I would add my two data points to the "rows" section and I would get 2 hierarchies. If I used a table, I didn't get all the summing and nice formatting. Something changed with how PowerBi treats the matrix and I simply couldn't replicate the examples. The last thing is probably the least important but the most annoying of all! As a programmer it was very frustrating to hear "If its not formatted, its not DAX code" or whatever. This is a blatant LIE!! You don't need newlines and you don't need to space out your parentheses in order for it to run. Most code can be written in one line if you want it to. Nobody says "If its not formatted then its not Java Code! Python is the first langauge that even cares about formatting and even it can be written on one line in most instances. Just say its best practice, not that its outright not DAX code.

I wish they would 1) speak slower 2) stop talking over each other and at the same time 3) do a screenshot of the formula we need to type out so that we dont need to pause and start the video so many times. Sometimes the formula is blocked by the arrow or the instructor's head.

There were a number of good points, but it really wasn't an introductory course as it assumed the viewer already had a certain level of knowledge about DAX. Would have been better to start at the real basics and build from there in little pieces, each of which is explained in detail. Additionally, it was difficult enough trying to filter through the narrator's heavy accent to follow what he was saying, but the occasional banter between him and the off-screen person became very distracting.

A good intro - thanks very much. Still having trouble getting my head around some of it so will have to do more training. ciao
