Cloudscape Inc was founded in 1996 to develop a Java database. In 1999 it was acquired by Informix, which was taken over by IBM in 2001. IBM developed Cloudscape as an embedded Java database, before handing it over to the Apache Software Foundation in 2004, which renamed it "Derby." Sun began supplying Java DB as a supported version of Derby in 2006.
From the Derby homepage: db.apache.org/derby
- Derby has a small footprint -- about 2 megabytes for the base engine and embedded JDBC driver.
- Derby is based on the Java, JDBC, and SQL standards.
- Derby provides an embedded JDBC driver that lets you embed Derby in any Java-based solution.
- Derby also supports the more familiar client/server mode with the Derby Network Client JDBC driver and Derby Network Server.
- Derby is easy to install, deploy, and use.
DBReplicator support for Derby is implemented, but needs testing.
