Object Relational Mapping, Persistence and Caching for Java {tm}Apache Cayenne{tm} is an open source persistence framework licensed under the Apache License, providing object-relational mapping (ORM) and [remoting services|CAYDOC:Remote Object Persistence Guide]. With a wealth of unique and powerful features, Cayenne can address a wide range of persistence needs. 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 as an Ajax-capable browser. Cayenne is designed to be easy to use, without sacrificing flexibility or design. To that end, Cayenne supports database reverse engineering and generation, as well as a Velocity-based class generation engine. All of these functions can be controlled directly through the CayenneModeler, a fully functional GUI tool. No cryptic XML or annotation based configuration is required\! An entire database schema can be mapped directly to Java objects within minutes, all from the comfort of the GUI-based CayenneModeler. ...

Cayenne supports numerous other features, including caching, a complete object query syntax, relationship pre-fetching, on-demand object and relationship faulting, object inheritance, database auto-detection, and generic persisted objects. Most importantly, Cayenne can scale up or down to virtually any project size. With a mature, 100% open source framework, an energetic user community, and a track record of solid performance in high-volume environments, Cayenne is an exceptional choice for persistence services.

Persistent Java classes are generated and synchronized with the mapping using the Modeler or alternatively with an Ant task. A database SQL schema can be generated from the Modeler and also with simple API calls. Change Notification Preferences View Online | View Changes
