Answer Posted / jidnesh
The Logical Database Structure of an Oracle include the
schema objects, data blocks, extents, segments and tablespaces.
schema objects means table, index, synonyms, sequences etc.
Data blocks are the smallest part of the oracle database
defined by DB_BLOCK_SIZE parameter.
A group of data blocks forms an extent.
An extents groups tends to segments, and lastly a group of
segment forms a tablespace.
