One$DB is an Open Source version of Daffodil DB. One$DB is a standards based (JDBC 3.0 and SQL 99 compliant), platform independent, footprint size database that can be embedded into any application and requires zero or minimal administration. Daffodil DB is the first Java database that has shown the capability to take on enterprise databases with its high performance in real time environments, Compiere compatibility being the best example so far. One$DB is exactly the same as Daffodil DB barring a few features and has been made available in both Embedded and Network editions.
