Question
Which type of mapping is not supported by Hibernate?
- One-to-One
- Many-to-One
- Many-to-Many
- Direct-to-Direct
Solution
Answer
In Hibernate, the mapping types that are commonly supported include One-to-One, Many-to-One, and Many-to-Many. However, the option "Direct-to-Direct" does not represent a recognized mapping relationship in Hibernate's ORM (Object-Relational Mapping) framework.
Explanation:
- One-to-One: This mapping defines a relationship where one entity is related to one other entity.
- Many-to-One: This mapping indicates that many instances of one entity are related to a single instance of another entity.
- Many-to-Many: This mapping shows a relationship where multiple instances of one entity are related to multiple instances of another entity.
Conclusion:
The "Direct-to-Direct" mapping is not a supported type in Hibernate, as it does not conform to the standard relationship definitions used in ORM practices.
