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.
