Rajat Khandelwal commented on LENS-974:
---------------------------------------

Another way of describing the two approaches is {{foreach resolver foreach 
fact}} vs {{foreach fact foreach resolver}}. The first is good for initial 
steps, but for later steps, the second becomes better. So we need a combination 
of both.

> 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.

> base_cube
>   |_fact1
>   |_fact2
>   |_cube_segment1
>      |_cube1
>         |_fact_11
>         |_fact_12
>         ... 
>       ...
>   |_cube_segment2
>      |_cube2
>         |_fact_21
