In this paper, we discuss issues involving temporal data fragmentation, temporal query processing, and query optimization in multiprocessor database machines. We propose parallel ...
Many data-driven social and Web applications involve collaboration and coordination. The vision of declarative data-driven coordination (D3C), proposed in [9], is to support coord...
We present a general method of parallel query processing that allows scalable performance on distributed inverted files. The method allows the realization of a hybrid that combin...
