HOLAP
HOLAP (hybrid online analytical processing) is a combination of ROLAP (Relational OLAP) and MOLAP (Multidimensional OLAP) which are other possible implementations of OLAP. HOLAP allows storing part of the data in a MOLAP store and another part of the data in a ROLAP store, allowing a tradeoff of the advantages of each. The degree of control that the cube designer has over this partitioning varies from product to product. == Vertical partitioning ==
In this mode HOLAP stores ''aggregations'' in MOLAP for fast query performance, and detailed data in ROLAP to optimize time of cube ''processing''.
