Big data

Definition

Big data refers to the vast volumes of structured and unstructured data generated from various sources at high velocity and variety. It encompasses data that is so large or complex that traditional data processing applications are inadequate to handle it. In smart manufacturing systems, big data plays a critical role in optimizing processes, enhancing decision-making, and improving overall efficiency by analyzing patterns and trends from massive datasets.
