Binary vote assignment grid quorum for managing fragmented database

Abstract

Replication usually referred as mechanism to increase availability and performance in distributed databases. Handling fragmented database replication becomes challenging issue since the distributed database is scattered into split fragments. Fragmentation in distributed database is very useful in terms of usage, efficiency, parallelism and also for security. In this paper, we manage fragmented database replication and transaction management using a new proposed algorithm called Binary Vote Assignment on Grid Quorum (BVAGQ). This technique combines replication and fragmentation. This strategy partition the database into disjoint fragments. The result shows that managing replication and transaction through proposed BVAGQ able to preserve data consistency. It also increases the degrees of parallelism. This is because by using fragmentation, replication and transaction can be divided into several sub-queries that operate on the fragments. © 2012 Springer-Verlag.
