Apache Derby is an open source database management system developed by the Apache Software Foundation. Because Derby is a pure Java program, Derby can be executed only if the operating system supports the Java virtual machine.

Derby's original prototype product, called Cloudscape,1999, was acquired by Informix and then by IBM along with informix. Cloudscape is also used as an embedded database in many IBM products. In 2004, IBM gave Cloudscape to Apache and changed its name to Derby.

Apache Derby is very small, and the core derby.jar is only 2m, so it can be used either as a separate database server or embedded in an application. Cognos8 BI's Content Store is the Derby database used by default, and you can see a directory called derby10.1.2.1 under the Cognos8 installation directory, which is the embedded 10.1.2.1 version of derby.

Derby provides an interactive man-machine interface tool, called ij, in the windows platform, this is a bat file, after execution into the command line interface, through the connect command can connect, create or start and stop the database. Note that all commands for ij must end with a semicolon (;).
