In the context of Caboodle, what does a 'snapshot column' refer to?

A 'snapshot column' in the context of Caboodle refers to a column that is designed to capture and hold specific points in time or historical states of data. This concept is essential for tracking changes over time; therefore, it often collects data as changes occur, which allows for the analysis of trends, performance, and other metrics. The term 'snapshot' implies that the information is taken at various periods, effectively creating a historical record of the data without losing previous states.

Given this understanding, options referring to a column that holds historical data or one that is always updated, while related, do not fully encapsulate the functionality of snapshot columns. A column that holds historical data might imply a static view rather than capturing ongoing changes, and a column that stores only unique values does not align with the concept of tracking time-related changes. Thus, the definition of a snapshot column directly relates to its ability to dynamically record changes as they occur, making it critical for comprehensive data analysis and history tracking.
