Each SQLBI Day is a different event with a different topic. To optimize the logistics, we have organized several SQLBI Days in a row in the same venue, but they cater to different audiences. For this first wave of SQLBI Days, we thought of three topics: one for DAX beginners and two for people who already know DAX well.

	Chicago	Amsterdam
For DAX Newbies
Introduction to DAX	Apr 30	May 27
For DAX Pros
Advanced DAX	May 1	May 28
First Steps in DAX Optimization	May 2	May 29
