Cayenne is a powerful, full-featured OpenSource Object/Relational Mapping (ORM) framework. Cayenne is written in Java and is intended for Java developers working with relational databases. Cayenne has been successfully deployed in production environments on high volume sites. Cayenne allows to reduce the development time in any database project by creating an object-oriented abstraction of the database schema. Development teams using Cayenne will be able to concentrate on the core business requirements and the data model instead of the SQL details.
