Concurrency control in a system for distributed databases (SDD-1)

Optimization of majority protocol for controlling transactions concurrency in distributed databases by multi-agent systems

In this paper, we propose a new concurrency control algorithm based on multi-agent systems which is an extension of majority protocol. Then, we suggest a clustering approach to get better results in reliability, decreasing message passing and algorithm’s runtime. Here, we consider n different transactions working on non-conflict data items. Considering execution efficiency of some different...

Performance of Distributed Optimistic Concurrency Control in Real-Time Databases

Concurrency control is one of the main issues in the studies of real-time database systems. In this paper different distributed concurrency control methods are studied and evaluated in real-time system environment. Because optimistic concurrency control is promising candidate for real-time database systems, distributed optimistic concurrency control methods are discussed more detailed way. We p...

Integrating Constraint Management and Concurrency Control in Distributed Databases

Chimera is a novel database language jointly designed by researchers at Politecnico di Milano, Bonn University, and ECRC of Munich in the context of the Esprit Project P6333, IDEA. Chimera integrates an object-oriented data model, a declarative query language based on deductive rules, and an active rule language for reactive processing. In this paper, we present the authors’ proposal for constr...

An Approach for Concurrency Control in Distributed Database System

Various concurrency control algorithms have been proposed for use in distributed database systems. Even, the large number of available algorithms, but the fact that distributed database systems are becoming a commercial reality, distributed concurrency control performance tradeoffs are still not well understood. In this paper, we focus on some of the important issues by studying four representa...
