Hibernate - impact of missing foreign key in database

If you have one to many mapping in your hibernate mapping file but do not have corresponding foreign key mapping on the tables in the database, then what is the impact to a Hibernate application?
Are constraints on the database optional?

Let's move this question over to a more appropriate forum.

From hibernate point of view yes the constraints are optional (i mean that hibernate will work without the constraint).
I agree. Here's the link:
