Wiki: Drill-down is a prominent feature of Flash charts which helps in building charts that are sensitive to mouse clicks. Using drill-down it is possible view additional data associated with each of the plots displayed on the chart. Flash charts also support tooltips, animation and offer many other types of interactive and aesthetic features. Flash charts are also capable of dynamic update. This means that the chart generator component can be linked to a dynamic data source. Dynamically updated charts are widely used on stock market websites to show current values of stocks. In most cases dynamic update is facilitated with the help of server side scripting languages like PHP, ASP.NET, ColdFusion, JSP etc.[1]

Wiki: 向下探究（drill-down）

主管支援系統強調圖形化的展示及友善的使用者介面，並具備強大的報告及向下探究（drill-down）能力。某方面來說，主管支援系統是一種全企業環境的決策支援系統，幫助高階主管分析、比較及聚焦於某些重要變數所呈現出來的趨勢，以方便他們監視企業之營運狀況、發現機會或問題。在業界裡，主管支援系統與資料倉儲的應用皆趨同達到同樣目的。

向下钻取(drill down)"Drill-down" in the information technology is to move from summary information to detailed data by focusing on an objective. It is used to describe articles that are stemmed from a single lead article that give a more in-depth or detailed information of the same subject (See Lead Article). These are users contributed articles such as critiques and comments, blogs which give the subject an in-depth and complete coverage. If the Lead Article is a prism, then the Drill-down Articles are the spectrum of the prism.
也就是在信息学中是指对对象的概要信息向具体信息的扩展
这里应该是指数据挖掘部件。

实际这里的drill-down不写出来也可以。就是指硬件统称下面的一个具体分类。
建议不译。

和钻没关系，具体的组件而已，连下一级别和下一层次的含义都没有
