What are the characteristics of data migration in Django?

Data migration in Django has the following characteristics:

1. Automation: Django’s data migration system can automatically track changes to models and generate corresponding migration files, thereby simplifying the process of data migration.
2. Flexibility: Django’s data migration system supports a variety of data migration operations, such as adding fields, changing field types, deleting fields, and even allows for custom data migration operations.
3. Data consistency: Django’s data migration system ensures that data consistency is maintained during the migration process, preventing data errors caused by migration operations.
4. Rollback support: Django’s data migration system supports rolling back migration operations, making it easy to revert to the previous state if an error occurs during migration.
5. Multiple environment support: Django’s data migration system can be utilized in various environments including development, testing, and production, making it easier for developers to perform data migration tasks.
