"Learn DAX", they said. "It'll be easy with your background", they said. Well, it turns out that it wasn't. Transitioning from SQL to DAX gave me nightmares and ulcers, and this session is for everyone who is looking over the edge and considering undertaking the challenge. It is in no way impossible, only frustrating, as DAX has a very different approach to data from what a SQL programmer is used to. In this introduction to the DAX language, I'll be putting a somewhat different spin on DAX from a beginners' standpoint.  I'll be going over the basic mental mistakes that many people trying to learn DAX do, how to solve them and how to put your brain on the right track!
