Кадом намудҳои пайвастшавӣ дар Hibernate вуҷуд доранд?

Hibernate дар defines the following types of relationships between entities:

1. Basic Association: A one-to-one relationship where one entity contains a direct reference to another (without using external tables for the relationship).

2. "One-to-Many" Associations:

   • One entity can be associated with many other entities.
   • Usually implemented using a foreign key in the "many" table.

3. "Many-to-One" Associations:

   • Many entities are associated with one other entity.
   • This is the inverse of the "One-to-Many" relationship.
   • Implemented via a foreign key in the "many" table.

4. "One-to-One" Associations:

   • Each entity of a type is associated with at most one entity of another type.
   • Implemented either through a shared primary key or via a foreign key in one of the tables.

5. "Many-to-Many" Associations:

   • Many entities of one type are associated with many entities of another type.
   • Requires a separate join table to store the relationships.

Hibernate provides annotations to describe these relationships:

• @OneToOne
• @OneToMany
• @ManyToOne
• @ManyToMany

It is also possible to configure cascading operations for automatic propagation of operations (like save, delete) to related entities.
