Available in PDF, EPUB and Kindle. Book excerpt: Database Concurrency Control: Methods, Performance and Analysis is a review of developments in concurrency control methods for centralized database systems, with a quick digression into distributed databases and multicomputers, the emphasis being on performance. The main goals of Database Concurrency Control: Methods, Performance and Analysis are to succinctly specify various concurrency control methods; to describe models for evaluating the relative performance of concurrency control methods; to point out problem areas in earlier performance analyses; to introduce queuing network models to evaluate the baseline performance of transaction processing systems; to provide insights into the relative performance of transaction processing systems; to illustrate the application of basic analytic methods to the performance analysis of various concurrency control methods; to review transaction models which are intended to relieve the effect of lock contention; to provide guidelines for improving the performance of transaction processing systems due to concurrency control; and to point out areas for further investigation. This monograph should be of direct interest to computer scientists doing research on concurrency control methods for high performance transaction processing systems, designers of such systems, and professionals concerned with improving (tuning) the performance of transaction processing systems.

Download or read book Parallel and Distributed Discrete Event Simulation written by Carl Tropper and published by Nova Publishers. This book was released on 2002 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Discrete-event simulation has long been an integral part of the design process of complex engineering systems and the modelling of natural phenomena. Many of the systems that we seek to understand or control can be modelled as digital systems. In a digital model, we view the system at discrete instants of time, in effect taking snapshots of the system at these instants. For example, in a computer network simulation an event can be the sending of a message from one node to another node while in a VLSI logic simulation, the arrival of a signal at a gate may be viewed as an event. Digital systems such as computer systems are naturally susceptible to this approach. However, a variety of other systems may also be modelled this way. These include transportation systems such as air-traffic control systems, epidemiological models such as the spreading of a virus, and military war-gaming models. This book is representative of the advances in this field.
Download or read book Concurrency Control in Distributed Database Systems written by W. Cellary and published by Elsevier. This book was released on 2014-06-28 with total page 366 pages. Available in PDF, EPUB and Kindle. Book excerpt: Distributed Database Systems (DDBS) may be defined as integrated database systems composed of autonomous local databases, geographically distributed and interconnected by a computer network.The purpose of this monograph is to present DDBS concurrency control algorithms and their related performance issues. The most recent results have been taken into consideration. A detailed analysis and selection of these results has been made so as to include those which will promote applications and progress in the field. The application of the methods and algorithms presented is not limited to DDBSs but also relates to centralized database systems and to database machines which can often be considered as particular examples of DDBSs.The first part of the book is devoted to basic definitions and models: the distributed database model, the transaction model and the syntactic and semantic concurrency control models. The second discusses concurrency control methods in monoversion DDBSs: the locking method, the timestamp ordering method, the validation method and hybrid methods. For each method the concept, the basic algorithms, a hierarchical version of the basic algorithms, and methods for avoiding performance failures are given. The third section covers concurrency control methods in multiversion DDBSs and the fourth, methods for the semantic concurrency model. The last part concerns performance issues of DDBSs.The book is intended primarily for DDBMS designers, but is also of use to those who are engaged in the design and management of databases in general, as well as in problems of distributed system management such as distributed operating systems and computer networks.
Download or read book Simulating Distributed Database Operating Systems and Evaluating Concurrency Control Protocol Performance Classic Reprint written by Frank Ramsey Professor of Economics Partha Dasgupta and published by Forgotten Books. This book was released on 2017-12-07 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Simulating Distributed Database Operating Systems and Evaluating Concurrency Control Protocol Performance As described in detail later, the distributed simulator has as its building block a site simulator. This single-site simulator is in effect a centralized database simulator with communication support. We have implemented a site simulator and used it as a centralized database simulator to obtain the results described in this paper. Our reasons for not simulating distributed concurrency control protocols at this point follow. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2006 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: A number of modern and important applications, such as tele-medicine systems, mobile internet stock trading systems, and traffic information and navigation systems, all require the support of efficient mobile database systems. Concurrency control constitutes an integral part of any transaction processing systems and thus deserves special attention. In this paper, we study concurrency control strategies, especially the optimistic approach, for mobile distributed databases, and postulate a controlled optimistic concurrency control algorithm, called Prudent-Waiting control, to reduce the number of transaction restarts. Our approach is able to reduce such restarts by recognizing more serializable schedules and prudently waiting to commit following the serialization order established. A detailed simulation model of a mobile distributed database has been constructed and a series of experiments have been conducted to evaluate the performance of the proposed approach. The results demonstrate that the new algorithm outperforms the optimistic concurrency control (with broadcast commit) and two-phase locking over a wide range of system workload.

Download or read book Concurrency Control and Reliability in Distributed Systems written by Bharat K. Bhargava and published by Van Nostrand Reinhold Company. This book was released on 1987 with total page 650 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major objective of a distributed system is to provide low coast availability of the resources of the system by localizing access and providing insulation against failures of individual components. Since many users can be concurrently accessing the system, it is essential that a distributed system also provide a high degree of concurrency. Research into algorithms has been focused on concurrency, consistency, failure detection, management of replicated copy, and commitment and termination of transactions. This book is a compilation of a subset of research contributions in the area of concurrency control and reliability in distributed systems, with brief explorations of interesting areas, including theoretical and experimental efforts.
