By gradually lowering the hierarchy level of data aggregated using frequently used items regardless of industry or business type, and referring to the aggregated items for analysis, it is possible to perform more detailed analysis of the aggregated results. There are advantages to being able to do so. Notes on drill-down analysis Drilldown is a method of digging deeper into items and analyzing data. Therefore, if you use this method from an off-target perspective, you may end up wasting your time by obtaining unnecessary data. I want data by period, but I can't get the data I want even if I drill down to the data by region. Therefore, when conducting an analysis, it is necessary to clarify from which perspective the drill-down will be performed, such as whether to perform an analysis by region, by store, or by period or product. there is.

How to use drill down Drilldown is a multidimensional cell phone numbers list data analysis method that refers to summary items and analyzes them by lowering the hierarchical level of data aggregation. It is often used in the sense of digging deeper, and is often used to check the data content at the time level of the aggregated results in the process of data analysis and perform more detailed analysis. Specifically, when developing a program, it is often used to analyze the reasons why there are many problems, by considering the location where the problem occurs, the person in charge, the cause of the problem, etc., and countermeasures. This method is extremely difficult to perform on paper, but using a system greatly reduces the difficulty of analysis. Therefore, it can be said that the spread of computers has made analysis using drill-down methods easier.



Difference between drill down and drill up There is a word called drill up which is the opposite of drill down. While drill-down gradually narrows the range of data, drill-up is an analysis method that gradually expands the range of data. Drilling is a method of changing the data aggregation range by combining drill-down and drill-up. Both drill-down and drill-up have their strengths, but it is important to choose an analysis method that suits the data you need. There is also a word called drill-through. Drill up and drill down are words that have opposite meanings, but drill through is completely different. Drilldowns are also used on websites. Drilldowns are also used on websites. It is mainly used on websites for smartphones, and drill-down is used for menus that open more items by tapping an item in the global navigation.
