What are the core interfaces of Hibernate?

beginner

Re-explain

The core types are Configuration, SessionFactory and Session. Transaction, Query and CriteriaBuilder complete the set.

Configuration: a class, not an interface. It reads the settings and creates the SessionFactory.
SessionFactory: the factory for Session objects. It is thread-safe and expensive to create.
Session: the main interface for persistence operations. It is not thread-safe.
Transaction: begins, commits and rolls back a database transaction.
Query: runs HQL and native SQL queries.
CriteriaBuilder: builds queries in code. It replaced Hibernate's legacy Criteria API, which Hibernate 6.0 removed.

Session extends JPA's EntityManager, so the same object also serves JPA code.
