Holap attempts to get best of both. HOLAP stores cube structue and preprocessed aggregates in multidimensional database which provides the fast retrieval of aggregate presents in MOLAP, howeve leaflevel data in RDBMS data mart. That leads to slower speed when getting leaf level values, Therefore HOLAP does not add latency to leaf level data.
