Although an optimistic approach has been shown to be better than locking protocols for real-time database systems (RTDBS), it has the problems of unnecessary restarts and heavy re...

This paper presents a technique that is capable of supporting two major requirements for concurrency control in real-time databases: data temporal consistency, and data logical co...

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...

Database systems for real-time applications must satisfy timing constraints associated with transactions. Typically, a timing constraint is expressed in the form of a deadline and ...

In a recent study, we have shown that in real-time database systems that discard late transactions, optimistic concurrency control outperforms locking. Although the optimistic alg...
