An extended approach to Non-Replicated dynamic fragment allocation in distributed database systems

The trends and necessity of running business organizations from multi-locations and multi-nations caused huge demand for distributed databases. The performance of any distributed database is highly depends on th e fragmentation of global relations and allocation of those fragments at different sites of the network. The data or fragment allocation ma y be performed either by static or dynamic ways. By efficiently allocating fragments in a dynamic way, performance of the distributed business organizations can be enhanced. This paper proposed an extended approach to dynamic fragment allocation in Non-Replicated distributed database systems which additionally include distance factor besides already existing factors like access threshold, access time constraints, and volume of data transmission. This ext ended fragment allocation approach will enhance fragment allocation in broader sense and also improves the overall performance of the system.
