Hibernate / Hibernate interview questions II

Hibernate: Difference commit() vs flush().

flush(): Flushing is the process of synchronizing the underlying persistent store with persistable state held in memory.it will update or insert into your tables in the running transaction, but it may not commit those changes.

Commit(): Commit will make the database commit.When you have a persisted object and you change a value on it, it becomes dirty and hibernate needs to flush these changes to your persistence layer.So You should commit but it also ends the unit of work.
