Answer Posted / rofali
In aggregate Fact tables data is aggregated at some level.
for example, we have a fact table for sales in which data
gets stored on daily basis. Now we can make another fact
table for sales which holds the sales data, aggregated at
weekly level. Now if we have to do repoting on weekly basis
we can directly use the aggregated fact table.this will be
the more efficient way.
