This is the balance between ROLAP and MOLAP.

HOLAP: Hybrid OLAP
This is a combination of the above two. This architecture has the MOLAP storage of summary data and this summary data has links to the detailed transaction level data in Data Warehouse RDBMS to enable user to drill down to the lowest level of detail. Apart from that it also allows direct access to the data in Data Warehouse, which is not considered worthwhile to be translated into OLAP cubes.
