Hi, I just wanted to point out that the latest release of LiquiBase now supports Derby. LiquiBase is a java-based LGPL tool for creating, managing, and applying database changes/refactorings.
It is similar in its goals to Rails' ActiveMigration, but works well with multiple authors and/or branches plus it includes rollback support and a database diff tool. If you're interested, check it out at http://www.liquibase.org Nathan
