Cloudscape (an IBM product) is a relational SQL DBMS written in the Java programming language.
Cloudscape does not require much memory or disk space, and it is easy to administer.
The Java 2 SDK, Enterprise Edition v. 1.3.1 includes a version of the Cloudscape DBMS (v. 4.0.6).
Cloudscape supports entry-level SQL-92.
In August 2004 IBM contributed the code to the Apache Software Foundation as Derby.
In March 2007 IBM announced that they would withdraw marketing and support for the Cloudscape product.
More information about Derby can be found at:
