What is Spring JPA?
Spring Data JPA, part of the larger Spring Data family, makes it easy to easily implement JPA based repositories. This module deals with enhanced support for JPA based data access layers. It makes it easier to build Spring-powered applications that use data access technologies.

It shows that JPA queries are 15% faster than their equivalent JDBC queries. Also, JPA criteria queries are as fast as JPQL queries, and JPA native queries have the same efficiency as JPQL queries.
Is JPA an ORM?
