Migrations in Django are a way to manage database schema changes. They allow developers to evolve the database schema over time while preserving existing data.

Migrations are a core feature of Django that facilitate the management of database schema changes in a structured and efficient manner. As applications evolve, the underlying database schema often needs to change to accommodate new features or improve performance. Django's migration system allows developers to define these changes through Python code, which is then translated into the appropriate SQL commands for the database. This process is crucial for maintaining the integrity of the database while enabling developers to evolve the schema over time. Migrations ensure that changes can be applied consistently across different environments, such as development, testing, and production. They also preserve existing data, allowing developers to modify the schema without losing important information. Django provides a robust set of commands for creating, applying, and reverting migrations, making it easy to manage complex schema changes. By leveraging migrations, developers can ensure that their database remains in sync with the application code, facilitating smoother development processes and minimizing the risk of data loss or corruption.
