CodeFutures has announced support for the IBM Cloudscape and Apache Derby databases by its FireStorm/DAO tool that generates the Java persistence code for accessing databases.
The press release is here:http://www.codefutures.com/java-persistence-cloudscape-derby/
The new release of FireStorm/DAO includes a database Schema Migration feature that makes it easier to migrate database schemas between different databases. Any SQL data types from the old database not supported by the new target database are automatically changed to the appropriate supported data types. This includes the Cloudscape and Derby data types, making it possible to migrate applications to these increasingly-popular databases.
The migration tool was added because of customer demand to migrate from existing databases to Derby.
The market move to Derby is possibly missed becuase Derby is a) open source and b) typically used as an embedded database.
