Big data

Definition

Big data refers to extremely large and complex datasets that traditional data processing applications cannot manage effectively. It is characterized by the three Vs: volume, variety, and velocity, which describe the immense size of the data, the diverse types of data collected, and the speed at which this data is generated and processed. Big data plays a crucial role in enhancing decision-making processes and generating insights that can lead to strategic advantages.
