The post outlines concrete engineering guidelines for both: use migration tools and never remove database columns, avoid SELECT *, don't enforce business logic in the DB, and avoid views. For APIs, update gateway schemas before implementation changes, accept unknown attributes gracefully (Postel's Law), only add enum values never remove them, and reserve versioning for major breaking changes. Following these practices also yields performance benefits by reducing unnecessary data transfer. ## Full article daily.dev links to this article rather than hosting it.
