Abstract: As a multidimensional index structure, the multidimensional hierarchical B + tree is introduced, on which an expandable multidimensional hierarchical cube (MH-cube) is set up. With the hierarchical semantics, MH-cube may perform quick query, data updates and schema update with high efficiency. A theoretical analysis shows that the MH-cube is superior to other kinds of cubes.

Key words: multidimensional hierarchies, cluster cube, range query, incremental update
