What does the terminology "drilling down" indicate in data analysis?

The terminology "drilling down" in data analysis refers to providing a more detailed view of the data. This process involves taking a high-level summary and breaking it down into more granular, specific information to gain deeper insights. For example, analyzing sales data might start at the aggregate level, showcasing total sales, and by drilling down, one could explore sales by individual products, regions, or time periods. This approach enables analysts to uncover patterns, trends, and anomalies that are not visible in the summary data, ultimately leading to more informed decisions and actions based on detailed findings.
