Yes, it makes your objects go to sleep. The use case is "you have a collection of objects that reference each other in memory. You want to say: Bam, put that structure like it is into a database ("put it to sleep"), and retrieve it again for me if I need it ("wake it up after winter is gone")." For this type of ORM Hibernate works fine. If you want to use a database as a database, it resists at every turn.
