Abstract:

Managing transactions with real-time requirements presents many new problems. In this paper we focus on two: How can we schedule transactions with deadlines? How do the real-time constraints affect concurrency control? We describe a new group of algorithms for scheduling real-time transactions which produce serializable schedules. We present a model for scheduling transactions with deadlines on a single processor memory resident database system, and evaluate the scheduling through detailed simulation experiments.
