Answer Posted / asha
2 purposes of factless fact
1. Coverage : to indicate what did NOT happen. Like to
answer questions like which product did not sell well in a
particular region.
2. Event tracking: To know if the event took place or not.
Like: Fact for tracking students attendence will not
contain any measures.
