Describe Yii’s approach to database migrations and version control.

Answer: Yii uses a structured approach to database migrations, allowing developers to manage changes to the database schema in a version-controlled manner. Migrations in Yii are PHP classes that define how to apply and revert changes, enabling the application of these changes across different environments consistently. They are stored in a specified directory and can be run via command-line tools to facilitate seamless updates and maintenance of the database schema, supporting both forward and backward migrations. This approach helps ensure that the database structure remains in sync with the application code over time.
