    MD5 vs. natural unique key

    FC60

      Hello,

      I start a new data warehouse project. In the ETLs for the ins/upd steps, I suggest to use MD5 and not the natural key (my sources are txt files from a mainframe).

      I need to explain to my project manager why I want to use md5 and not the natural key. He don't accept "...because md5 is the good practice...", he don't accepta dogmas, he want some exemples.

      Can you give me some exemples?

       

      Many thanks.
