I will probably never need DAX but I have to say that I've book marked this incredible article for if I ever do. What a great thing you've done here... makes a great "Rosetta Stone" and makes for very quick learning by someone who already knows SQL (which, I suspect, would be the better part of the majority). Well done, good Sir, and thank you for taking the time to write and publish this article.

First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.
