Question: If I have table T1 and table T2 T1 has 250 cols and 10,000 rows T2 has 2 billion rows and 10 cols Which one would be Fact table and which one would be Dimension table and why ?

Answer: Whether table T1 and T2 are dimension or fact table depends on the information they store. If the all the measures are
In T1 with dimensions key in it then T1 table is fact and if T1 is having a pk and textual information then it is dimension and visa versa.

Idealy the number of row in fact table is very high. In this
case it looks like T2 may be the fact and T1 may be the
dimension. But cann't be said for sure as the information
given is incomplete.
