Abstract With the growth of information technology and computer networks, there is a vital need for optimal design of distributed databases with the aim of performance
improvement in terms of minimizing the round-trip response time and query transmission and processing costs. To address this issue, new fragmentation,
data allocation, and replication techniques are required. In this paper, we propose enhanced vertical fragmentation, allocation, and replication schemes
to improve the performance of distributed database systems. The proposed fragmentation scheme clusters highly-bonded attributes (i.e., normally accessed
together) into a single fragment in order to minimize the query processing More >
