Data Analysis Expressions ( DAX ) is the new query language or expression language of Powerpivot. It also has a rich set of functions which are almost similar to Excel functions. A dictionary of all the DAX functions are available for download from PowerPivot-info.com. Most of the functions sound very similar to Excel, except the Time-Intelligence functions.
The functions listed in the Time-Intelligence section looks very much aligned towards the structure and usage that we find in the Date / Time dimension. I wonder why all this information is not available on MSDN yet, or at least I am not able to locate down on MSDN.
