How do you handle database schema migrations and version control in backend systems?
Database schema migrations and version control in backend systems are essential for seamless development and deployment. To handle this, we use a combination of techniques including database migration tools, version control systems, and continuous integration pipelines.
In database migration, we use scripts or code to make changes to the database schema in a controlled and reproducible manner. This allows us to easily modify the schema as our application evolves.
Version control systems like Git help us keep track of changes to our codebase, including database migration scripts. We can create separate branches for different features or bug fixes and merge them when ready.
To ensure that migrations are applied consistently and automatically, we integrate them into our continuous integration pipeline. This allows us to run tests, build and deploy the application, and apply any necessary database migrations automatically.
