Owning side of the relationship

[Karnati Sudhakar]

Hi All,

The owner of the relationship is purely our taste or is there any rule for that?

In EJB 3 in Action for it is given as

For bidirectional one-to-many relationships,ManyToOne is always the owning side of the relationship.

Is it an advice or rule to be followed?

May be i am asking this question because i did not understand the entity relationships fully

This is a rule : The many side of one-to-many / many-to-one bidirectional relationships must be the owning side, hence the mappedBy element cannot be specified on the ManyToOne annotation.
