Hey everybody!

I'm just configuring a new table in Hibernate and are wondering what a <one-to-many> declaration might be useful for. Is it just for saving the E/R in the XML-files, or does it also give you an advantage, like if I declarate a <one-to-many> on an Order-class, which therefore references a Customer-class that I can ask something like



Cause til now I always left those <one-to-many> things out, cause I found it not useful.

Thanks for any help!

Entity associations is basically what Hibernate is all about. Check some of the Tutorials linked on the website (External Documentation) and read the "Parent/Child Relationship" chapter in the reference.
