wht is degenerated dimension ?it's uses?
Answer Posted / kvchowdary
degenerate dimension is a data dimension that is stored in
the fact table rather than a separate dimension table. This
eliminates the need to join to a dimension table. You can
use the data in the degenerate dimension to limit or 'slice
and dice' your fact table measure
