Introduction to the Solution

EclipseLink supports access to NoSQL data through the JavaEE Connector Architecture. You must use a JCA adapter (provided by EclipseLink, a third party, or custom built).

Most NoSQL data is hierarchical in form so using embeddable objects is common. Some NoSQL adaptors support XML data, so NoSQL mapped objects can use XML mappings when mapping to XML.
