LiquiBase is a DBMS-independent library for tracking, managing and applying database changes. All database changes (structure and data) are stored in an XML-based descriptive manner and checked into source control. LiquiBase has the following features: * Supports merging of changes from multiple developers * Works well with code branches * Allows you to manage production data as well as various test datasets * Works in an environment where multiple machines will be attempting to migrate the database concurrently * Supports automated change-applying or generation of SQL scripts that can be approved and applied by a DBA * Supports rolling back changes * Can create database \"diff\"s and can generate change logs from them
