I'm looking for a good MDX book that deals specifically with MDX. I'm working on SSAS 2012 and don't know if anything has changed (the last time I was writing MDX was on SSAS 2008 about 5 years ago).
I used to own (but seem to have misplaced) Microsoft® SQL Server® 2008 MDX Step by Step and thought it was fine but if someone has can recommend something better that would be great!
