Abstract: Intra-operator(or partitioned) parallelism is a well-established mechanism for achieving high performance in parallel database systems. However, the problem of how to exp...
Traditionally, optimizers are “programmed” to optimize queries following a set of buildin procedures. However, optimizers should be robust to its changing environment to gener...
Classification, which involves finding rules that partition a given da.ta set into disjoint groups, is one class of data mining problems. Approaches proposed so far for mining cla...
