Managing Database Migrations with Alembic

Short summary

Alembic is a Python tool that manages SQLAlchemy database schema changes safely and consistently. Workflow: update your SQLAlchemy models, run `alembic revision --autogenerate` to generate a migration file, review the generated code manually, then run `alembic upgrade head` to apply changes to the database. This keeps schema and code in sync across environments.

• •Alembic auto-generates migration files from SQLAlchemy model changes
• •Always manually review migrations before applying to catch errors
• •Keeps database schema and Python models synchronized in version control
