Hibernate interview questions

!!! Hibernate interview questions !!!

What are the Instance states in Hibernate?

The instance is not, and has never been associated with any persistence context. It has no persistent identity
(primary key value).
The instance is currently associated with a persistence context. It has a persistent identity (primary key
value) and, perhaps, a corresponding row in the database. For a particular persistence context, Hibernate
guarantees that persistent identity is equivalent to Java identity (in-memory location of the object).
The instance was once associated with a persistence context, but that context was closed, or the instance
was serialized to another process. It has a persistent identity and, perhaps, a corrsponding row in the database.
For detached instances, Hibernate makes no guarantees about the relationship between persistent
identity and Java identity.
