South (migrations tool)

South is a tool used in Django, a web development framework, to manage changes in a database schema over time. When you update your application's data models, South helps track these changes and automatically applies them to the database, ensuring consistency. It simplifies the process of evolving your database structure—adding tables, modifying fields—without losing data. Essentially, South acts as a version control system for your database, making it easier to develop, deploy, and maintain web applications that depend on a evolving database architecture.
