What is Index Segmentation ?..

Answer / hari krishna

A segment is a part of relational data base and consists of
one or more extents. Each extent is further divided into
blocks. Every segment has an index for holding all of its
data for quick data retrieval. Index segments can be created
explicitly by using the CREATE INDEX command. Storage
parameters for the extents of the index segment can be
specified along with this command.
