In the world of Hibernate, we classify objects into three categories: transient, persistent, and detached. A transient object lacks an association with a database session. On the other hand, a persistent object is linked to an active database session. Finally, a detached object is a persistent object that has been disconnected from its session.
When an object is initially created, it falls into the transient category. To make it persistent, you need to add it to a session using either the save() or persist() method. Once an object becomes persistent, any modifications made to it will be automatically synchronized with the database.
If you find yourself needing to eliminate an object from the database, the delete() method comes in handy. It performs two tasks: detaching the object from the session and removing it from the database.
