Optimistic locking is an alternative to using exclusive locks when you
have the possibility of concurrent, conflicting updates in your database.
The basic principle is you allow any and all clients to issue updates and
rather than preemptively synchronizing all data modifications (which is
what happens with exclusive locks) you are "optimistic" that updates won't
interfere with one another and the updates will only fail when they do
in fact interfere with one another.
