Bit map Indexes are used with the columns having low
cardianality like Gender(M/F),Marital Status.The benefit of
it is that it requires a small space comapred to the case
if a B-Tree index is created on the same column of the
table.
Bit map Indexes are useful in the systems where data is not
getting updated frequently.
