• Data cube can be viewed as a lattice of cuboids
• The bottom-most cuboid is the base cuboid
• The top-most cuboid (apex) contains only one cell
• How many cuboids in an n-dimensional cube with L levels?

\[ T = \prod_{i=1}^{n}(L_{i}+1) \]

• Materialization of data cube
• Materialize every (cuboid) (full materialization), none (no materialization), or some (partial materialization)
• Selection of which cuboids to materialize
• Based on size, sharing, access frequency, etc.
