Oracle is a database s/w.
It can be divided into multiple partition.
Each partition will be identified by one global database.
By default when you install oracle,we have only 1 partition,which is identified by one global database.
ORCL for oracle enterprise edition(changable)
XE for oracle express Edition.
Each Db may contain many user,
and each user may contain multiple tables
and each table may contain multiple rows and columns
Thats the story of Oracle Architecture
