Free registration required

Executive Summary

Data Replication is the technique of using multiple copies of a server can help database systems meet the stringent temporal constraints of current time-critical applications, especially Internet-based services to resource for superior availability and act to development of high Priority performance concurrency control mechanisms. Each copy is called a replica. A requirement for realizing the benefits of replication, however, is the development of high performance concurrency mechanism. Current applications, such as Web-based services, electronic commerce, mobile telecommunication system. The main goal of replication is to improve availability and consistency since a service is available even if some of its replicas are not.
