Apache Derby Database Engine and Embedded JDBC Driver

 Apache Derby is an open source relational database implemented entirely
 in Java.
  * Derby has a small footprint -- about 2.6 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.
 .
 This package includes the database server, the embedded JDBC driver and
 localisations.
