#04 - OneToOne Entity Relationship JPA | JAVA PERSISTENCE API JPA | Tutorial | Java

✅ JPA Entity Relationship, One To One Relationship
The relations are more effective between tables in the database. The entity classes are treated as relational tables, the relationships between Entity classes are as follows:

- @ManyToOne Relation
- @OneToMany Relation
- @OneToOne Relation
- @ManyToMany Relation

In this video, we are going to learn the OneToOne Relationship in Java Persistence API (JPA).
In the One-To-One relationship, one item can belong to only one other item. It means each row of one entity is referred to one and only one row of another entity.

We are going to use the Student entity defined in the previous video and we are going to implement a new Entity called: School.
During this video, we are going to use the H2 database for database operations.
