Mathematical Framework for A Novel Database Replication Algorithm
Sanjay Kumar Yadav, Gurmit Singh, Divakar Singh Yadav · International Journal of Modern Education and Computer Science · 2013
In this paper, the detailed overview of the database replication is presented.Thereafter, PDDRA (Pre-fetching based dynamic data replication algorithm) algorithm as recently published is detailed.In this algorithm, further, modifications are suggested to minimize the delay in data replication.Finally a mathematical framework is presented to evaluate mean waiting time before a data can be replicated on the requested site.
