Liquibase

Liquibase is an open source database-independent library for tracking, managing and applying database schema changes. It has the ability to roll changes back and forward from a specific point. It makes it easy to define database changes in a format that's familiar and comfortable to each user and then automatically generates database-specific SQL for you.
