I'm not a real expert, but is this design very similar to Oracle database storage engine? I think they also use logs for undo and page level transaction locks and such if I'm not mistaken.

Yes, it's similar to the in-place row update system used by not just Oracle, but also Microsoft SQL Sercer and probably other databases.
