We live in the world of “Big Data.” That is the new way people are trying to describe this sea of digital facts, figures, products, books, music, video, and much more. All of this is at our fingertips through computers and smartphones. And there is a lot of data. The global data volume is expected to grow exponentially from 44 zettabytes (a zettabyte is one trillion gigabytes) in 2020 to 163 zettabytes by 2025. No wonder people say we live in the world of “Big Data.”
