Database version control and schema changes

The podcast discusses the importance of database version control, specifically focusing on schema changes. It emphasizes the need for managing schema changes in conjunction with data changes, such as altering data types or columns. It compares the evolution of code version control systems from naive and lock-based systems to the decentralized systems like Git. While application code version control is well-established, the podcast highlights that many teams still struggle with implementing a similar system for their databases, leading to issues with collaboration, deployments, and continuous integration.
