Designing the Model Structure

[araryes]

For creation of new application, the end user (business) gives just only one sheet â€" which he wants as Output.

Is there any logical mechanism by which I can decide â€" how many different input cubes are required.

What happens if I just create only one dcube for this entire sheet and project that itself as the output. Obviously it serves the purpose â€" but I feel that this may not be the best practice? Hope my question is understood, not able to articulate clearly
