hi,
what is hibernate ?

its called O-R mapping ?

O-R mapping stands for "Object-Relational mapping". Java is Object Oriented,
and MySQL (for example) is Relational. So an O-R mapping creates a mapping
(a one-to-one correspondence) between an class in an object oriented
language and a table in a relational database.

is it an API ?

its a Software/tool ?

is it Software which has Database in it ? does it comes with a DB ?

can anybody please tell me in the simplest way whats this hibernate
means ?

It's basically so that you can persist (save) your objects in a
database, and then perform queries to load the objects back out of the DB.
You download a JAR, add it to your project, and it exposes an API which
takes care of saving your objects to the DB at the appropriate time. It
doesn't come with a database itself; you'll have to install one seperately,
and then configure Hibernate to connect to the DB.
