JPA Training

The Java Persistence API Training Course is a step-by-step introduction to build applications using the new Java persistence framework.This course is especially for those beginners who want to develop POJO?s based-applications interacting with the relational database. It uses the release version of EJB 3.0, defined in Java EE 5.0 specification.

JPA Stands for Java Persistence API, also known as EJB3 Persistence or JEE 5 Persistence. It is the new Sun standard object/relation-mapping and lightweight framework for creating Java database applications. It lets you develop persistent classes and POJO objects to the relational database using following common Java idiom such as - association, inheritance, polymorphism, composition and the Java collections framework.

Here is the video tutorial of "JPA Training Course":

JPA Training Objectives

In this course you will learn how to persist your class POJO's with relational database using JPA Object-Relational mapping technology. After completing this course, you will be confident for implementing and maintaining Object-Relational persistence in your JPA application, including all necessary client-side and server-side programming.

JPA Training Course Prerequisites

Before learning this course, we are assuming that the candidate has good background in the following technologies:

Intermediate knowledge of Core Java programming.
Creating basic web applications using Servlet & JSP.
Some familiarity with SQL, relational databases, and the Java Database Connectivity (JDBC) interfaces will be helpful.
