Abstract
An ultra-shared-nothing parallel database system includes at least one master node and multiple slave nodes. A database consisting of at least one fact table and multiple dimension tables is partitioned and distributed across the slave nodes of the database system so that queries are processed in parallel without requiring the transfer of data between the slave nodes. The fact table and a first dimension table of the database are partitioned across the slave nodes. The other dimension tables of the database are duplicated on each of the slave nodes and at least one of these other dimension tables is partitioned across the slave nodes.
