Persistent object stores which are in some sense leading edge deal
explicitly with versioning, i.e., they automatically create and manipulate
(or otherwise
allow for programmatic) version history graphs of persistent objects. In
dealing with
this important issue up front they also realize additional benefits, such
as simply avoiding certain tedious locking problems.

Two products which come to mind are the Matisse OODBMS and the Kala
Persistent Store.
