Concurrency Control in Distributed Geographical Database Systems
نویسنده
چکیده
This paper discusses concurrency control in distributed geographical database systems. A geographic data server providing transactional services must be designed to handle both longand short-duration transactions. The main challenges are identified as: (1) preserving the isolation property when concurrent transactions perform read and write operations on pages; (2) ensuring that search and other operations on the spatial access structure appear isolated; and (3) whatever method that is chosen they must provide feasible solutions with respect to performance. Existing approaches are discussed and presented.

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...
متن کاملEvaluation of Concurrency Control Schemes on Distributed Systems
Concurrency on a massive scale is required to meet the needs of today’s increasingly distributed systems. To better understand how current concurrency control schemes work on distributed systems, this paper reports an evaluation of concurrency control schemes for online transaction processing (OLTP) workloads on distributed database management systems (DBMS) with a variable number of nodes. Fiv...
متن کاملDistributed Concurrency Control Performance: A Study of Algorithms, Distribution, and Replication
Many concurrency control algorithms have been proposed for use in distributed database systems. Despite the large number of available algorithms, and 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 attempt to shed light on some of the important issues by studying f...

متن کاملPerformance 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...
