Document Summary

The computer prepares a report, which usually contains details of each batch, together with an indication of whether the totals agreed or disagreed. Agree run-to-run totals: reconciling totals prepared before a computer process has begun to totals prepared at the completion of the computer process. Tickler file: manual file of documents, or a computer file, that contains business event data that is pending further action. One-for-one checking: detailed comparison of the individual elements of two or more data sources to determine that they agree. Edit checks (programmed checks) are most often validation routines built into application software. The purpose of edit tests is to examine selected fields of input data and to reject those transactions whose data fields do not meet the pre- established standards of data quality. Validity check (e. g. , m = male, f = female) Limit check (e. g. , hours worked do not exceed 40 hours) Reasonableness check (e. g. , increase in salary is reasonable compared to base salary)
