What method records data at a defined interval regardless of value changes?

The method that records data at defined intervals, regardless of value changes, is the forced method. This approach is designed to capture data at specified time intervals to ensure continuous data recording, providing a consistent dataset for analysis. This is particularly useful in scenarios where time-based data is critical, even if the underlying values remain unchanged during certain periods.

The forced method operates independently of the actual data value, focusing solely on the schedule for recording. As a result, it assures that data points are created at regular intervals, which can be crucial for time-series analysis and historical record-keeping.

In contrast, other methods such as cyclic recording may involve capturing data only under certain conditions, while delta methods typically rely on changes in values to trigger recordings. These alternative methods do not fulfill the requirement of recording at fixed intervals without consideration of changes in data values.
