Cayenne is a powerful, full-featured, opensource framework created for developers working with relational databases. it seamlessly maps any relational database to Java objects, reducing development time and adding considerable functionality to any application which requires a database. Developers using Cayenne will be able to concentrate on the core business requirements and the data model instead of the SQL details. The application can then be easily moved to any JDBC-capable database. In addition to management of persistent Java objects mapped to relational databases, Cayenne provides a plethora of features including single method call queries and updates (including atomic updates of all modified objects), seamless integration of multiple databases into a single virtual data source, three tier persistence with caching on the remote client, paging of results, record locking, and many more features. JPA compliance is in progress.
