Cayenne ~~seamlessly~~ binds one or more database schemas directly to Java objects, managing [[atomic commit]] and rollbacks, [[SQL]] generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via [[Web Services]]. Or, with native [[XML]] serialization, objects can be ~~even~~ further persisted to non-Java ~~clients - such~~clients—such as an Ajax-capable browser.▼ == Background == ▲'''Apache Cayenne''' is an open source persistence framework licensed under the Apache License, providing object-relational mapping (ORM) and remoting services.

It was released under the Apache license<ref>[http://objectstyle.org/cayenne/lists/cayenne-devel/2002/11/0000.html Apache-style voting through mailing lists]</ref> from its first release in July 2002.<ref>[http://objectstyle.org/cayenne/lists/cayenne-user/2002/06/0000.html ~~July~~Cayenne ~~2002~~Alpha Release].</ref> In early 2006 the project moved from Objectstyle to the [[Apache Software Foundation]] and in December of 2006 was promoted to be a top level project of Apache.<ref>[https://blogs.apache.org/foundation/category/projects The Apache Software Foundation Blog]</ref> Notable milestones in Cayenne's history include the release of Apache Cayenne 3.0 in May 2010<ref>[http://www.silicon.co.uk/workspace/apache-releases-details-of-cayenne-java-framework-8256 Silicon.co.uk news]</ref><ref>[http://www.eweek.com/development/apache-delivers-details-of-cayenne-3.0 eWeek news]</ref> and the release of Apache Cayenne 3.1 in the fall of 2014.<ref>[https://sdtimes.com/apache-cayenne/apache-cayenne-updated-with-highly-configurable-runtime/ Software Development Times]</ref> ==See also== [[Apache OpenJPA]] ==References== {{Reflist}} ==External links== {{Official website\|https://cayenne.apache.org/}} [http://www.objectstyle.org Objectstyle] [http://www.theserverside.com/tt/articles/article.tss?l=Cayenne Cayenne article on theserverside] {{Jakarta Persistence}} ~~{{apache}}~~ {{Apache Software Foundation}} [[Category:~~Java~~Apache ~~platform~~Software Foundation projects\|Cayenne]] [[Category:Java ~~enterprise~~(programming ~~platform~~language) libraries]] [[Category:Object–relational mapping]]
