For example, you might have several original columns - such as
Country - which together are categorised as an
Address. In most countries, addresses include a postal code (or zip code), which unambiguously identifies the street.
Address category comes with a
Postal Code property, which tells your bunker which of the original columns contains the code. When you use your bunker to assign a group of columns to the
Address category, you can also configure that property.
