Hi Prakash,


In object-relational mapping products, the ability to directly manipulate data stored in a relational database using an object programming language is called transparent persistence.


I am sending you a link. Following link provide you many running example with description and more information about hibernate.

Thanks.

Transparent Persistence means any class can be persisted
without:
1 Any implementation of specific interfaces
2 No required persistence superclass


Persistence API Usage:

1. API Order
a.) Get Session
b.) Begin Transaction
c.) Save your object by calling save(),
d.) saveOrUpdate()
e.) Commit and close transaction

2. Normally this should be wrapped in a DAO layer
