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 ...
: In order to meet their temporal constraints, current applications such as Web-based services and electronic commerce use the technique of data replication. To take the replicatio...
- Performancestudiesof concurrencycontrol algorithms for conventional database systems have shown that, under most operating circumstances, locking protocols outperform optimistic ...
Due to its potential for a high degree of parallelism, optimistic concurrency control is expected to perform better than two-phase locking when integrated with priority-driven CPU...

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...
