To access and persist data between Java object(Plain Old Java object)/ class and relational database, we can use JPA. Upon Object-Relation Mapping (ORM), it follows the mechanisms. It has the runtime EntityManager API and it is responsible for processing queries and transactions on the Java objects against the database.
