MDX measure to DAX conversion I needed a little help on working with MDX and DAX. Recently I have just started working with these two terms and am having a little trouble figuring out the differences and possible examples of how they work. 

The articles I have read online are giving me a little trouble and I am finding it hard to understand. It would be great if someone could, maybe, kindly explain it in simple words what they are and what they do?

Thank you so much for the help!
MDX &amp; DAX are query languages for OLAP cubes. 

MDX is used on multidimensional OLAP cubes and is used by many vendors.

DAX is Microsofts own query language and can only be used in a tabular OLAP cube or within Excel. 

Assuming you are using Microsoft  SSAS you must choose which type of cube you want when you install SSAS.

If you (or someone else) has already installed SSAS then you need to find out   if its Multidimensional or Tabular, and then use the appropriate query language.
