Role of bitmap indexes to solve aggregation problems - Data warehousing

Explain the role of bitmap indexes to solve aggregation problems.

Bitmap indexes are useful in connecting smaller databases to larger databases. Bit map indexes can be very useful in performing repetitive indexes. Multiple Bitmap indexes can be used to compute conditions on a single table.

Explain the role of bitmap indexes to solve aggregation problems.

Bitmaps are useful for starting schema for the purpose of joining large databases small databases. For performing logical operations on the databases, bit arrays and the answer queries are used. To handle Gender differentiation, bit map indexes are efficient. Bit map indexes also capable of performing repetitive tasks with much larger efficiency.
