JPA Training

Workshop Length

4 days

Description

JPA Stands for Java Persistence API, also known as EJB3 Persistence or Java EE Persistence. It is the Java standard for creating object oriented Java database applications. There are now many implementations that support the JPA specification (Hibernate, Kodo, OpenJPA, EclipseLink, TopLink and DataNucleus to name a few).

Smart Soft has been conducting JPA workshops since it was first introduced. And we were teaching JDO, Hibernate and EJB (JPA's precursors) workshops before that. We are JPA experts. In fact, JPA has been our most popular workshop for the past 4 years.

This workshop focuses on the practical aspects of using JPA. Having created dozens of JPA applications ourselves, we know where the common pain points are. In this workshop, we cover the details of the JPA specification (API, query language, mapping, etc.) but we also focus on best practices and common JPA design patterns.

Prerequisites
