If you are a back-end developer, you are often faced with having to migrate your database schema with each new release.

The framework called Liquibase can make it easier for you when you need to upgrade your database schema.

In this article, I’ll explain how Liquibase can be used in a Java project, with Spring/Hibernate, to version the database schema.

How does Liquibase work?

Changelog

Liquibase works with Changelog files (the list of all the changes, in order, that need to execute to update the database).

There are 4 supported formats for these Changelogs: SQL, XML, YAML, and JSON.
