Calling Post is what posts the changes into the datasets cache of updates.
What happens when ApplyUpdates is called is it takes all the updates from
the cache and applies them on the server and flags the update in the cache
as applied. At that point the person can either CommitUpdates or
CancelUpdates such that the cache of changes is made permanent or removed
from the server via rollback and reset to non applied in the buffers.
There are distinct reasons for using cached updates instead of 2 tier
