Fact less fact is nothing but the fact table that it doen't
contains any measures, but can see the count of occurring or
events are called Factless fact table.
example, ::No. of accidents in month.
if i elaborate it, number of accidents in one month give a basic count, by this you will not be able to make a business intelligence out of it. Hence this can not be a measurable.
It's just for statistical purpose. IN this case measurable is
"At what speed accidents took place?" here speed
is measurable fact i.e 75 kmph., 90 kmph., etc.,
based on speed factor you can have BI. Each event count of
accident is assigned to speed. hence BI says, by controlling
speed limit we can control accidents.
"This count of accidents is just statistical information
you can not control it directly.
Thank you.
