Hi,

I'm studying for the JPA certification and I've read about element collections in the book I'm reading(Pro JPA 2, Mastering the Java persistence), but I could not see the benefits of that, neither how it's better than a "common" relationship.

Does someone know what benefits it brings or a possible source of information about it? (I'm gonna read the specification soon, maybe this helps ..)

I use element collections when I simply need a primitive datatype in a collection. You may declare a new relationship but then you need a new class just for one field. Its too bloated imo.
