git/svn/... use store intermediate versions of the source code, so that applying all patches becomes O(log N) instead of O(N). But that's just an optimization.

NoSQL systems work in a similar way - they can store the 'tip' of the data, so that they don't have to reapply all the patches all the time. However, the latest data view can be rebuilt if required.
