#06 ManyToOne Entity Relationship JPA | JAVA PERSISTENCE API JPA | Tutorial | Java | Jakarta смотреть онлайн

✅ JPA Entity Relationship, Many 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 Many to One Relationship in Java Persistence API (JPA).
In the Many-To-One relation between entities, one entity is referenced with another entity that contains unique values. In a relational database, these relations are applicable by using foreign key/primary key between tables.

We are going to add a new entity called Teacher to implement the relation between Teacher and School entity.

During this video, we are going to use the H2 database for database operations.
