Weekly reports provide data on performance trends.
To make weekly and/or daily reporting effective, Teradata recommends that you establish threshold limits. Note that filtering on key windows having a 24-hour aggregate of weekly aggregates that includes low-used weekends and night hours distorts the report.
Furthermore, Teradata recommends that you analyze the longest period possible. This avoids misleading trend data by softening temporary highs and lows.
