Big data

Definition

Big data refers to the vast volumes of structured and unstructured data generated at high velocity from a variety of sources. This concept encompasses the collection, storage, analysis, and visualization of massive datasets that traditional data processing applications cannot handle effectively. Big data's significance lies in its potential to uncover insights and trends that can inform decision-making, optimize operations, and enhance customer experiences in business.
