Abstract

The performance of database transaction processing system can be profoundly affected by the concurrency control method employed since it is necessary to preserve database integrity in a multi-user environment. In addition to satisfying the consistency requirement as in traditional database system, real-time database systems must also satisfy timing constraints. In this study we present a virtual run policy for the restarted first run optimistic transactions and compare its performance with optimistic concurrency control in firm real-time database system.
