Fact table basically consists of Foreign keys which are
taken from the primary keys of all dimension as well as
facts.
So, for this reason take all the dimensions as Unconnected
lookups and try to take the foreign keys and at the same
time try to use the avaialble sources and make all possible
facts with the necessary transformations.
