In addition to drill-down navigation, it's also possible to "roll up" or aggregate groups of concepts. Here, it's simple to create a new concept named "NorthHiSupply Units" that has been defined in a completely ad-hoc manner by applying Visage's "Compose" operation to the highlighted units.
Successive drill down and roll up permits the user to construct complicated data queries in a powerful and intuitive way. |
