JPA Tutorial - Java Persistence API

In this tutorial, we will learn JPA in-depth with Hibernate as Implementation.

JPA stands for Jakarta Persistence API (JPA), formerly known as Java Persistence API.

JPA is just a specification that facilitates object-relational mapping to manage relational data in Java applications. It provides a platform to work directly with objects instead of using SQL statements.
