An efficient transitive closure algorithm for distributed databases

Because most of the recognizable queries in deductive databases can be transformed into transitive-closure (TC) problem, the development of efficient algorithms to process the different forms of TC problems within the context of large database systems has recently attracted a large amount of research efforts. However, the parallelization of the computation of TC is still a new issue and there are only a few and recent parallel TC algorithms. Most of these parallel algorithms mere developed for shared-nothing architectures. We present a new efficient algorithm for full TC problem for shared-nothing architecture. Using simulation, we also study and examine the performance of the algorithm
