Abstract
This chapter gives an overview on multilevel transactions and its
generalization toward open nested transactions. The main features
of these transaction models are the following: first, semantic
properties of operations can be exploited to relax the isolation
of concurrent transactions; sedcond, as a consequence, atomicity
is achieved by compensation rather than state-based undo;
and third, subtransactions can be made persistent independently
of their commit state, that is, global visibility of their updates.
