KeyAccess is a light-weight object-relational mapping (ORM) tool for Java, using existing databases as the starting point to generate a domain model. Its main goal is to reduce and sometimes eliminate manual updating between your domain object model and the underlying databases, while still being able to use arbitrarily complex SQL queries. In addition, KeyAccess doesn’t mandate a special architecture or framework – it will work in any application using JDBC.
