Chapter 1. Introduction

1.1. Intended Audience
1.2. Lightweight Persistence

Enterprise Java Beans 3.0 Persistence (EJB persistence) is a specification from Sun Microsystems for the persistence of Java objects to any relational datastore. EJB persistence requires J2SE 1.5 (also referred to as "Java 5") or higher, as it makes heavy use of new Java language features such as annotations and generics. This document provides an overview of EJB persistence. Unless otherwise noted, the information presented applies to all EJB persistence implementations.

[Note]Note

This document describes the Public Draft of the EJB 3.0 persistence specification.

For coverage of Kodo's many extensions to the EJB persistence specification, see the Reference Guide.

1.1. Intended Audience

This document is intended for developers who want to learn about EJB persistence in order to use it in their applications. It assumes that you have a strong knowledge of object-oriented concepts and Java, including Java 5 annotations and generics. It also assumes some experience with relational databases and the Structured Query Language (SQL).
