Apache Cayenne is an open source persistence framework licensed under the Apache License, providing remoting services and object-relational mapping (ORM). 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 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.
