1 Naturally, the only way to favor more than one hierarchy (per dimension) in
clustering is to maintain redundant copies of the cube (Sarawagi & Stonebraker,
1994), or to treat different hierarchy paths as separate dimensions (Markl,
1999). The latter results in an increase of the cube dimensionality, rendering
clustering even more difficult (Weber, 1998).
