Abstract
Transactions in real-time active databases have the notion of activeness where transactions are generated by external effects and another transaction. In this paper, we improve the real -time active concurrency control algorithm by applying Thomas' write rule and considering relationship between transactions fired by active rules. We also present the experimental results of our algorithm comparing other real-time active concurrency control algorithms. The experimental results show that our algorithm has superior performance with respect to the raio of transactions satisfying deadline.
