Concurrency Control Protocol for Nested Transactions in Real-Time Databases
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...

Using importance of transactions and optimistic concurrency control in firm real-time databases
In a real-time database system, it is difficult to meet all timing constraints due to the consistency requirements of the underlying database. However, when the transactions in t...

On Optimal Concurrency Control for Optimistic Replication
Concurrency control is a core component in optimistic replication systems. To detect concurrent updates, the system associates each replicated object with metadata, such as, versi...

Measured Performance of Time Interval Concurrency Control Techniques
This paper reports on an implementation of Bayer's Time Interval concurrency control method and compares it to the performance of a conventional timestamp method. The impleme...
