Explanation

A slowly changing dimension (SCD) is a dimension whose attributes change gradually over time. The 'person responsible for a cost center' can change when responsibilities are reassigned, making it a classic SCD example. Dates don't change, and customer/order relationships or purchase order values aren't dimensions.
