What is drilling?
In terms of Oracle Discoverer, drilling is a technique that enables you to quickly navigate through worksheet data, finding the answers to the questions facing your business. As mentioned, depending on your needs, you can use drilling to view the data you're working with in deeper detail or, in contrast, drill it up to a higher level.

So, Discoverer supports a set of drilling tools, including the following:
Drilling up and down
Drilling to a related item
