Yes, Naveen.
You are true.
But we can say the segments are the database objects which use/occupy the space in Database and can be in creased in size. i.e. the segments are your Tables, Indexs, Rollback segments, lob segments. Segments are used in the database to calculate the size in use for the objects.
There are other oracle objects i.e. View, Synonym, Sexquence, Pl/Sql (Packages, Procedures, FUnctions, Triggers etc). These objects in general will not occupy much space in the database.
To know the list of segment types in the database
SQL> select distinct segment_type from dba_segments;
To know the list of object types in the database
SQL> select distinct object_type from dba_objects;
With Best Regards,
