Join tables are good when you want to avoid null values

When should you use @OneToOne with @JoinTable in Spring Data JPA?

A @OneToOne relationship is self explanatory (at least on the surface level). One customer has one address. One author has one book..

But using the JPA @OneToOne annotation specifically means that you are utilizing an ORM provider (like Hibernate) under the hood to implement the code/logic for creating tables, relationships (foreign keys, primary keys) so that you don't have to worry about it.

JPA defines runtime annotation interfaces like @OneToOne. It is up to the ORM providers (like Hibernate) to implement this. At runtime, Hibernate will generate the code you need to generate the tables you need.

How does a @OneToOne relationship work in Spring Data JPA?

@JoinTable gives you the best of both worlds because you can both allow null values AND not store them :)
