Value (Data in highlight). This feature is the purpose of Big Data technology. This view is well expressed by the International Data Corporation4 when saying that Big Data architectures are: “designed to economically extract value from very large volumes of a wide variety of data, by enabling high-velocity capture, discovery, and/or analysis”. This value falls into two categories: analytical use (replacing/supporting human decision, discovering needs, segmenting populations to customize actions) and enabling new business models, products and services [12,10].
