Hi all !

Just to make a little answer about differences  between Palo and Mondrian.

Firstly, it's not the same approach. In OLAP technologie you have :
 - ROLAP, like Mondrian, the engine is based on a relational database to
expose dimensions

 - MOLAP, like Palo, the engine has is own data storage and save data
directly in dimensional aspects...

You also have HOLAP... and hybrid approach...

You have to pay attention about Palo if you store too many data inside a
cube... In a relational database you don't ask you this question...
