database system which provides the framework to
study the performance of timestamp ordering concurrency
control. We exhibit an analytical solution, which
has been tested with extensive simulation. The accuracy
seems to be very high. We assume perfect and
also imperfect clocks for synchronization and quantify
the way in which local clock inaccuracies affect the
phenomenon of transaction conflicts.1 aBouras, Christos1 aSpirakis, Paul  uhttp://telematics.upatras.gr/telematics/publications/performance-models-perfect-and-imperfect-clocks-timestamp-ordering-distributed
