From the inception of mainframes to modern cloud storage and mobile devices, the amount of data produced has risen steeply. Today, humans produce large amounts of data as they go about their day-to-day activities and business operations. For decades, much of the data produced was not used for analysis or business decision purposes. Nevertheless, data has always been indispensable for both small and large enterprises. Nowadays due to digitalization, the importance and value of data has become an integral part of business decisions. Take the example of online retailers who base business predictions on the basis of user clicks and purchasing patterns—actions that generated a huge amount of data. By applying analytical tools to this data, the retailer gleans valuable information for decision making. One can imagine the flood of data pouring from a smart house or a smart city.
