Track, version, and deploy database changes
Changelogs and tracking tables allow Liquibase to help teams track and version database changes and deploy changes.
- Track and version database changes
Developers know which changes have been deployed to the database and which changes have not yet been deployed. - Deploy changes
Liquibase compares the changelog against the tracking table and only deploys changes that have not been deployed to the database.
Easily author database changes
Liquibase makes it easy to define database changes in a format that’s familiar and comfortable to each user — SQL, XML, JSON, or YAML.
Liquibase uses changelogs to represent a changes to your database.

Deploy the same changes across multiple database types
Liquibase allows you to specify the database change you want using SQL or several different database-agnostic formats, including XML, YAML, and JSON. Developers can abstract the database code to make it extremely easy to push out changes to different database types. The abstract format options also offer more flexibility and many more features over a formatted SQL changelog.

State and migration-based deployments
Choose state-based or migration-based deployments which, at their root, are about the source of truth. Define how you want the database to look at the end or write the database change scripts for ultimate flexibility and to ensure the performance of database changes.
