Active databases and real-time databases have been important areas of research and the benefits of integrating them have been recognized. However, there has not been much work done in the area of transaction processing in active real-time databases. This paper deals with the problem of assigning priorities to transactions in real-time active databases. We present various protocols for assigning priorities to transactions and evaluate them using a simulator. Our results demonstrate that dynamically changing the priorities of transactions depending on their behavior (triggering rules), yields a substantial improvement in the number of triggering transactions that meet their deadline.
