sql - Row Inserted and Updated Time in Fact Table -

-

i see there importance in having row inserted , row last updated fields in fact table. not find standard data warehouse or reference says thing do. uncertain whether because bad practice; if why should so? if because of data size, see 8bytes full date field.

any appreciated!!!

there's nothing talking whether it's or bad practice because include creation time , updated time if need them or ever need them.

it's "good thing do" if need access columns , "bad thing do" if table never require columns.
