EclipseLink is an advanced, object-persistence and object-transformation framework that provides development tools and run-time capabilities that reduce development and maintenance efforts, and increase enterprise application functionality.
+
 
+
Using EclipseLink, you can integrate persistence and object-transformation into your application, while staying focused on your primary domain problem by taking advantage of an efficient, flexible, and field-proven solution (see [[EclipseLink/UserGuide/JPA/Introduction/Object-Persistence Impedance Mismatch|What Is the Object-Persistence Impedance Mismatch]]).
+
 
+
EclipseLink is suitable for use with a wide range of Java 2 Enterprise Edition (Java EE) and Java application architectures (see [[#EclipseLink Application Architectures|EclipseLink Application Architectures]]). Use EclipseLink to design, implement, deploy, and optimize an advanced, object-persistence and object-transformation layer that supports a variety of data sources and formats, including the following:
+
* Relational–for transactional persistence of Java objects to a relational database accessed using Java Database Connectivity (JDBC) drivers.
+
* Object-Relational Data Type–for transactional persistence of Java objects to special purpose structured data source representations optimized for storage in object-relational data type databases such as Oracle Database.
+
* Enterprise information system (EIS)–for transactional persistence of Java objects to a nonrelational data source accessed using a Java EE Connector architecture (JCA) adapter, and any supported EIS record type, including indexed, mapped, or XML.
+
* XML–for nontransactional, nonpersistent (in-memory) conversion between Java objects and XML Schema Document (XSD)-based XML documents using Java Architecture for XML Binding (JAXB).
+
 
+
EclipseLink includes support for EJB 3.0 and the Java Persistence API (JPA) in Java EE and Java SE environments including integration with a variety of application severs including: Oracle WebLogic Server, OC4J, Glassfish/SunAS, JBoss, and IBM WebSphere application server. EclipseLink lets you quickly capture and define object-to-data source and object-to-data representation mappings in a flexible, efficient metadata format (see [[Introduction to EclipseLink Application Development (ELUG)#Working with EclipseLink Metadata|Working with EclipseLink Metadata]]).
+
 
+
The EclipseLink runtime lets your application exploit this mapping metadata with a simple session facade that provides in-depth support for data access, queries, transactions (both with and without an external transaction controller), and caching.
