Tell about your experience with database migrations.

Database migrations are a way to manage changes to the database schema in a controlled and repeatable manner. In my experience, I have used migration tools (such as Flyway or Liquibase) for:

• Automating schema changes during deployment.
• Versioning the database structure.
• Ensuring schema consistency across different environments (development, testing, production).

The typical process involves writing migration scripts (e.g., SQL files) that add or modify tables, indexes, constraints. These migrations are then applied sequentially, ensuring the database is always up-to-date.

This helps avoid issues with manual schema changes, facilitates team collaboration, and automates the deployment process.
