Hi,
What is the Difference between ROLAP and MOLAP.
Thank you.
 
ROLAP means that the storage type for the OLAP cube is relational. This forces the aggregations to be driven from the database itself. In general this allows for quicker cube build times, but greater query times. This also forces you to have access to the relational database to view the cube details.

MOLAP means that all of the aggregations are stored in the OLAP cube. This allows for quicker query times but slower cube builds. It also means that you can view the cube details while not connected to the DB.

A combination (hybrid) of the two, HOLAP, is also available. This allows you to utilize benefits from both of the previous types.
