Drill down is what that takes a user from a more general view of the data to a more specific one simply by clicking a mouse. For instance, a report that shows sales revenue by state can allow the user to select a particular state, by simply clicking on it. The user can also see sales revenue by county or city within that state.

A report that allows a user to navigate to a different layer of data granularity by navigating and clicking on a specific data element on a web page or in an application is a A drill down report.
