Ch Kashif
OLAP can process complex queries and give the output in less than 0.1 seconds,
for it to achieve such a performance OLAP uses aggregations. Aggregations are
built by aggregating and changing the data along the dimensions. Possible
combination of aggregations can be determined by the combination possibilities of
dimension granularities.
