Abstract
A computer readable storage medium includes executable instructions to receive a request for data from a multi-dimensional cube divided into partitions distributed across nodes supporting a shared nothing distributed multi-dimensional database. The request is transformed into physical access layer operators in a tree structure. The tree structure is reduced into an index scan operator.
