Answer Posted / durgaprasad
Index-- use to locate needed records from database tables
quickly.BW uses two types
---1. bitmap and 2. B-tree.
b-tree is for regular database tables and bitmap is for fact
tables and aggregate tables
Bitmap index - Bit map index uses maps of bits to locate
records in table.This indexs are very effective for Boolean
operators of where class of a select statement.when the
codinalality of a collum is low bit map index size will be
small there by reducing i/o volume.(which improves the
performance)
