Training: Introduction to Data Persistence with JPA

Ref. JPA
Not certifying


The Java Persistence API Training Course is a step-by-step introduction to building applications using the new Java persistence framework. JPA Stands for Java Persistence API, also known as EJB3 Persistence or JEE 5 Persistence. It is a 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.

Participant profiles

  • Beginner developers who want to develop POJO’s based-applications interacting with the relational database


  • Understand how to persist your class POJO’s with relational database using JPA Object-Relational mapping technology
  • Be confident for implementing and maintaining Object-Relational persistence in your JPA application, including all necessary client-side and server-side programming


  • 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
