as you mentioned:"Palo save data directly in the server" as a data
So if use mondrian , is it better to use a DW(like Infosight or Bizgres) to
build the multi dimensional table first
in order to increase performance?

> Firstly, it's not the same approach. In OLAP technologie you have :

> - MOLAP, like Palo, the engine has is own data storage and save data

> 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...
