In a distributed database system (DDBS), the data is partitioned into smaller databases and distributed over multiple sites in a computer network. Associated with a DDBS are functions like query processing and concurrency control. Traditionally in DDBS research, the computer network has been considered a performance bottleneck and a lot of research eeort(More)
In this paper, we consider an application of high speed wide area networks, viz., that of distributed database systems (DDBS). In a high speed environment, although the transmission delay decreases, the propagation delay (communication latency) now becomes the throughput thwarting factor. Existing concurrency control (CC) protocols do not address the(More)
