An object of value type has no database identity, and objects of value type are dependent on the owning entity object. The lifespan of the value type is bound by the lifespan of the owning entity. Entities that have a collection of value types need to be mapped to an appropriate collection interface from the Java API. For entities to have a collection of value types, you need to have a separate table with the entity’s primary key as a foreign key.
