Strategies for resolving inter-class data conflicts in mixed real-time database systems
Although many efficient concurrency control protocols have been proposed for real-time database systems, they are mainly designed for the systems with a single type of real-time transactions. Their performance objective is usually to minimize the number of deadline missing of soft real-time transactions or to guarantee the deadline satisfaction of hard real-time transactions. Due to the very different performance requirements of hard and soft real-time transactions, existing realtime concurrency control protocols may not be suitable to Mixed Real-time Database Systems (MRTDBS), where different types of real-time transactions, and even non-real-time transactions, may co-exist in the systems. In this paper, we propose strategies for resolving data conflicts between different types of transactions in a MRTDBS so that the performance requirements of each individual transaction type can be satisfied and, at the same time, the overall system performance can be improved. The performance of t...
