- Performancestudiesof concurrencycontrol algorithms for conventional database systems have shown that, under most operating circumstances, locking protocols outperform optimistic ...
In this paper we present a concurrency control algorithm that allows co-existence of soft real-time, relational database transactions, and hard real-time database pointer transact...
Time-critical scheduling in real-time database systems has two components: real-time transaction scheduling,which is related to task scheduling in realtime operating systems, and ...
Data replication can help database systems meet the stringent temporal constraints of current time-critical applications, especially Internet-based services. A prerequisite, howev...
