Definition

Best articulated by Tom Brown from The Information Lab as:

Blue fields are discrete – they contain a FINITE number of values – for example – the field REGION may contain the values North/South/East & West, but no others

Green fields are continuous – they could contain an infinite number of values – for example the PRICE of an item could be any value along a number line
