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...

Dynamic Adjustment of Serialization Order Using Timestamp Intervals in Real-Time Databases
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...

Using Dynamic Adjustment of Serialization Order for Real-Time Database Systems
Studies in [7,8, 91 concluded that for a variety of reasons, optimistic concurrency control appears well-suited to real-time database systems. Especially, they showed that in a re...

Dynamic Real-Time Optimistic Concurrency Control
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...

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...
