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...
In this paper we consider real-time concurrency control for the nested transaction model. We analyze problems that have pure optimistic and pessimistic approaches. As the solution...
Various concurrency control algorithms di er in the time when con icts are detected, and in the way they are resolved. In that respect, the Pessimistic and Optimistic Concurrency ...
Data replication can help database systems meet the stringent temporal constraints of current time-critical applications, especially Internet-based services. A prerequisite, howev...

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 ...
