[java] What is “the inverse side of the association” in a bidirectional JPA OneToMany/ManyToOne association?

Simple rules of bidirectional relationships:

1.For many-to-one bidirectional relationships, the many side is always the owning side of the relationship. Example: 1 Room has many Person (a Person belongs one Room only) -> owning side is Person

2.For one-to-one bidirectional relationships, the owning side corresponds to the side that contains the corresponding foreign key.

3.For many-to-many bidirectional relationships, either side may be the owning side.

Hope can help you.
