Data mart is considered to be a subset of datawarehouse, If the data is missing for primary key and the data source can be gathered from the list of entity derived from dimensions, but data mart entity can be fullfilled from the data located in central server system in datawarehouse as per proposed concept of KIMBAL. Need feedback for my answer.
