Describe your experience with database migrations in previous projects.

In previous projects, for database migrations, I used tools such as Alembic (for SQLAlchemy) and Django Migrations. The process typically involved creating migration scripts that described changes to the database structure — adding or removing tables, modifying fields, indexes, etc. After writing the migrations, I ran them in a test environment to ensure correctness and no data loss.

Example with Alembic:

# Creating a migration
alembic revision --autogenerate -m "Add email field to users table"

# Applying the migration
alembic upgrade head

It is also important to control the order of migrations and keep them in a version control system so that the team can synchronize database changes.
