What does persistence object means in Hibernate architecture?

Persistent object is nothing but an instance of POJO class that we create to represent rows in the table in the database.

According to hibernate-doc an instance of POJO class representing table in database goes through 3 states.


When a POJO instance is in session scope, it is said to be persistent i.e hibernate detects any changes made to that object and synchronizes it with database when we close or flush the session.
