摘要
The invention provides a method and apparatus for distributing data of a table across a parallel data base system having a plurality of interlinked database nodes. The table is partitioned in accordance with a predetermined partitioning arrangement and data of the table is distributed across a subset of the nodes in accordance with the partitioning arrangement. The partitioning arrangement can comprise horizontal or vertical partitioning. The partitioning arrangement can comprise a partitioning map defining the relationship of partitions of the table to said subset of nodes.
