MDX was initially developed by Microsoft for its SQL Server analysis products, though it has since become an independent standard. It's been around long enough now that there are many MDX tutorials and references, most notably:
- http://msdn.microsoft.com/en-us/library/ms145506.aspx
- http://en.wikipedia.org/wiki/Multidimensional_Expressions
Note: MDX implementations vary, and many MDX documentation resources are specific to certain niche products or standards. Not all MDX functions and extensions are supported in Pentaho Analysis.
