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. 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. 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. ...

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. News Andrus Adamchik posted on Sep 26, 2011 Cayenne 3.1M3 is Released We are glad to announce 3.1M3 release of Cayenne. This is an important milestone on our way to Beta. In fact there is a good chance that the next release will be announced as Beta. Upgrade to M3 is strongly recommended to all 3.1 users, as it contains some critical bug fixes. The highlights of the M3: Core API improvements - cleaner vararg APIs in ObjectContext and Cayenne classes, ObjectContext.localObject(Object), etc. Switching more of the internals to DI (query cache providers, … Read more… Edit Andrus Adamchik posted on Jun 21, 2011 Cayenne 3.0.2 is Released We just released a maintenance version of stable Cayenne 3.0 branch. It has 19 bug fixes and minor improvements, e.g. a performance improvement for MySQL (JDBC batching). If you are a 3.0.x user, this is certainly a recommended upgrade. A full list of closed jiras is below: CAY-1500 MySQL JDBC Batching CAY-1403 Method "readNestedProperty" Should Resolve Through Iterative Invocations onto DataObject and Not Complete Within Cayenne.readNestedProperty CAY-1432 java.io. … Read more… Edit Andrus Adamchik posted on Mar 08, 2011 Cayenne 3.1M2 is Released We keep improving Cayenne 3.1 with the new M2 milestone release. If you've already experimented with 3.1, M2 is a must-have upgrade - it fixes a number of bugs that affected runtime stability (CAY-1515, CAY-1519). If you haven't, maybe it is time to try it out? Usual disclaimer applies about M2 being an early alpha and the new APIs being subject to change. … Read more… Edit Andrus Adamchik posted on Dec 02, 2010 Cayenne 3.1 - it's alive! Cayenne 3 isn't resting on its laurels. It is still growing and developing, and today we are pleased to announce the first milestone of version 3.1. This is not a beta and 3.1 is not yet feature-complete, but it gives users an insight into the direction Cayenne is heading in and an opportunity to give us feedback. The key features added to 3.1 so far are: Built-in Dependency Injection container, statics-free and singleton-free runtime. Simplified single-domain projects. … Read more… Edit Cayenne Modeler Cayenne is distributed with CayenneModeler - a complete GUI mapping tool that supports reverse-engineering of RDBMS schemas, working with database mappings and generation of Java source code for the persistent objects. 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
