Key factors driving the growth of the data science market include the increasing adoption of data-centric business strategies, the growing need for actionable insights, and the dramatic emergence of innovative technologies such as Wi-Fi connectivity, sensors, and IoT (Internet of Things), which generate massive amounts of data every second.
