Subj:   Re: ETL process question
From:   David Wellman


The last project that I worked on included file headers/trailers mainly for this requirement. Headers and trailers contained a file identifier and sequence number which was checked against a control table on Teradata prior to the main processing (from memory we used fastload to populate work tables, then checked the headers against the control table then did the real work). The trailers also contained date, record count and a hash-total.
