Introduction to [Flyway](http://www.FlywayDB.org/), the open-source tool for migrating your database changes between your dev-test-QA-prod systems. Evolve your database schema easily and reliably across all your instances. Like version control for your code, but for your database.
If you manage the changes in the structure of your database with a rag-tag bunch of SQL scripts, a pile of emails, some shouts across the cube walls, luck, and desperate hope, then you may be interested in learning how to use Flyway or a similar tool to organize the process into a reliable, repeatable, testable, automated, and stress-free system.
