transient - New objects created in the Java program but not associated with any hibernate Session are said to be in the transient state.
persistent - An object which is associated with a Hibernate session is called a Persistent object. While an object which was earlier associated with Hibernate session but currently it's not associated is known as a detached object. You can call the save() or persist() method to store those objects into the database and bring them into the Persistent state.
detached - You can re-attach a detached object to hibernate sessions by calling either update() or saveOrUpdate() method.
