Today, businesses of all sizes must make more data-based decisions than ever before to stay competitive. Large amounts of data, including those generated by the user or customer interactions, connected social media, devices, and hardware, can provide extraordinary insights and intelligence when properly analysed. These data-driven insights can help companies increase profitability, business growth, and service quality, improve product offerings, and make smarter business decisions. Hence the storage, analysis, and processing of such big amounts of data have led to the birth of Big Data Analytics.
