What is Liquibase?
Liquibase is an open-source database schema change management solution which enables you to manage revisions of your database changes easily. Liquibase makes it easy for anyone involved in the application release process to:
- Eliminate errors and delays when releasing databases.
- Deploys and Rollback changes for specific versions without needing to know what has already been deployed.
- Deploy database and application changes together so they always stay in sync.
