> With cube segmentation a cube can have multiple cubes and all these child
> cubes together will make the cube complete.
> CubeSegmentation and CubeFactTable will sit together, which means it can
> belong to only one base cube. A base cube can have one or more cube
> segmentations. Fields of segmentation will be intersection of all columns of
> its cubes. Segmentation will have weight to compare with its buddies (facts
> or other segmentations). Also it can have start and end time defined or it
> can derive from its underline facts.
> eg:
> base_cube
> |_fact1
> |_fact2
> |_cube_segment1
> |_cube1
> |_fact_11
> |_fact_12
> ...
> ...
> |_cube_segment2
> |_cube2
> |_fact_21
> |_fact_22
> ...
> ...
