Method and apparatus for loading data into a cube forest data structure

摘要

A device and method is disclosed for loading data into and updating a data structure known as a cube forest for use in a batch-load-then-read-intensively system. The device and method perform loading and updating functions efficiently. Hierarchically split cube forests provide a method for efficiently duplicating information, and can be optimized to reduce update and storage costs. Cube forests including hierarchically split cube forests are most appropriate for read-intensive, update-rarely-and-in-large-batches multidimensional applications in an off-the-shelf (low cost) hardware environment. A method and an apparatus for loading data into and updating a cube forest are disclosed herein.
