Big Data isn’t just big – it’s fast. Information specialist Thorsten Engel says by analysing data in real time and matching it against what is known about each customer, retailers can make accurate snap decisions. “The algorithms can learn in real time what is more effective at driving click-through and conversion,” Engel says.
