SCRUM: Agile database development

Fowler, Martin and Sadalage, Pramod. Evolutionary Database Design

Abstract:
Over the last few years we've developed a number of techniques that allow a database design to evolve as an application develops. This is a very important capability for agile methodologies. The techniques rely on applying continuous integration and automated refactoring to database development, together with a close collaboration between DBAs and application developers. The techniques work in both pre-production and released systems.
