schema evolution

Stairway Step

As database development scales across multiple contributors, concurrency becomes an inherent aspect of the process. Changes that are individually correct may still conflict when developed against a shifting baseline. This level introduces a disciplined approach to managing parallel changesets by controlling their scope, identifying overlap, and resolving conflicts through realignment. By ensuring that only one changeset retains its original baseline while others are adapted accordingly, deployments remain predictable and consistent. Once released, changesets are treated as immutable, and further evolution proceeds through new, forward-only changes.

Stairway Step

Stairway to Reliable Database Deployments introduces a progressive approach to managing database changes with clear intent, predictable rollback, and explicit behavioral guarantees. Starting from change design and moving toward execution and coordination in complex environments, the Stairway provides a conceptual framework for deploying database changes safely and consistently, independent of specific tools or automation platforms.
