Flyway and Liquibase are two popular database migration tools with different philosophies. Flyway uses a simple convention-over-configuration approach with plain SQL files and versioned naming, making it ideal for single-database projects. Liquibase offers more features including database-agnostic migrations through XML/YAML changesets, built-in rollback support, and preconditions, making it better suited for enterprise applications supporting multiple databases. The choice depends on project complexity, database requirements, and team preferences.
