1 Introduction

EclipseLink is a powerful and flexible Java persistence framework for storing Java objects in a data store, such as a relational database or a NoSQL database, and for converting Java objects to XML or JSON documents. EclipseLink provides APIs and a run-time environment for implementing the persistence layer of Java Platform, Standard Edition (Java SE platform), and Java Platform, Enterprise Edition (Java EE platform) applications.

EclipseLink implements Java Persistence API (JPA), Java Architecture for XML Binding (JAXB), and other standards-based persistence technologies and also includes extensions beyond those standards.
