In a datawarehouse, considering EDW and datamart as separate applications, when data is transformed from EDW to Datamarts , do we consider it External Output from EDW? Is it one EO from EDW or mutliple EOs ( each per source system) from EDW ?
I checked various papers on Dataware house couting but none of them mention about EO from data warehouse to Datamart.
