jpa

In this article you will learn how to quickly get started with JPA. I will be using NetBeans and MySQL database to store data using JPA. If you have MySQL running, all you have to do is follow the steps below.

Java Persistence API (JPA) abstracts the database interactions and treats them as objects rather than simply queries. Since these queries are now objects, the principles of Object-Oriented Programming (OOP) can come into play including, encapsulation, abstraction, inheritance, and polymorphism. Persistence in the java language is actually not a new concept at all. Many implementations have been created in the past including, EDJ, JDO, Hibernate, and Toplink to name a few. JPA was designed with the idea of simplifying the Enterprise JavaBean (EJB) programming model.
