multidimensional online analytical processing and
relational online analytical processing. In MOLAP data is
stored in form of multidimensional cubes. The advantages of
this mode is that it provides excellent query performance
and the cubes are built for fast data retrieval. All
calculations are pre-generated when the cube is created and
can be easily applied while querying data.In ROLAP, the
data is stored in relational databases this model gives the
appearance of traditional OLAP’s slicing and dicing
functionality. The advantages of this model is it can
handle a large amount of data and can leverage all the
functionalities of the relational database.
