Has anyone come across a good method for keeping their source code and database schema in sychronized version control so that you can roll back code and schema simultaneously if need be?

In particular I would be super stoked if there were something out there like springloops (www.springloops.com- web based SVN manager) with a web GUI that keeps your DBs in sync and allows you to easily deploy from dev to production.

Is this just wishful thinking or has anyone seen it?
