1) cascade="none", the default, tells Hibernate to ignore the association.
2) cascade="save-update" tells Hibernate to navigate the association when the
transaction is committed and when an object is passed to save() or
update() and save newly instantiated transient instances and persist changes to
detached instances.
3) cascade="delete" tells Hibernate to navigate the association and delete persistent
instances when an object is passed to delete().
4) cascade="all" means to cascade both save-update and delete, as well as
calls to evict and lock.
5) cascade="all-delete-orphan" means the same as cascade="all" but, in addition,
Hibernate deletes any persistent entity instance that has been removed
(dereferenced) from the association (for example, from a collection).
6) cascade="delete-orphan" Hibernate will delete any persistent entity
instance that has been removed (dereferenced) from the association (for
example, from a collection).
