Explain the role of Session interface in Hibernate? Java Hibernet

•    In hibernate, the Session interface wraps a JDBC connection, holds a mandatory (first-level) cache of persistent objects, used when navigating the object graph or looking up objects by identifier and is a factory for Transaction
•    Session session = sessionFactory.openSession();
•    The Session interface is the primary interface used by Hibernate applications.
•    It is a single-threaded, short-lived object representing a conversation between the application and the persistent store.
•    It allows you to create query objects to retrieve persistent objects.
