The main objective of data replication in a distributed database system is to provide high data availability for transaction processing. Quorum consensus (QC) methods are commonly applied to managing replicated data. In this paper, we present a new QC method. The proposed QC method is highly fault-tolerant, and fully distributed (i.e., each site in a distributed system is equally weighted). Further,...
This paper investigates the problem of allocating relational database fragments to a network to minimize the overall communication cost for processing a given set of transactions. This problem is known as NP-hard. In this paper, we transfer the optimal data allocation problem to an integer linear program subject to various constraints, such as network load capacity and storage capacity of each individual...
