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.}, journal = {American Journal of Applied Sciences}, publisher = {Science Publications} }
