what is the difference between aggregate table and fact
table ? how do you load these two tables ?

Answer Posted / chithra. k

Fact tables generally contains measures and the composite
key, which is generally a combination of foreign keys from
the respective dimension tables.

Aggregate tables are summary tables which contains the
summary information say for eg:total sales revenue (for a
quarter).

So the difference is in the granularity.Fact tables store
date in more detail level, but in aggregate tables the
granularity is high.
