Content:Object Relational Mapping, Persistence and Caching for JavaApache Cayenne is an open source persistence framework licensed under the Apache License, providing object-relational mapping (ORM) and remoting services. 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. Cayenne team is in the process of building a spec-compliant open source JPA Provider. News

Apache Cayenne team is glad to announce the first milestone release of Cayenne 3.0.

Cayenne team is glad to announce a new release of Cayenne 2.0 and 1.2 branches. The new release features a long list of bug fixes and is a recommended upgrade for the current users. As always there is a patch-level compatibility between 1.2.3 and 2.0.3.... As work continues toward Cayenne 3.0, many new features Welcome to the new Cayenne web site. It is the culmination of lots of work from Bruce Martin (graphic design, html and css coding), Andrus Adamchik (chief guidance, server scripting and content writing) and Ari Maniatis (design concept, Confluence wrangling and content). And of course the content written for Cayenne by a number of people over the years. This design should degrade gracefully on older browsers. It automatically exports from Confluence,... Cayenne Modeler
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. |
