Big data

Definition

Big data refers to the vast volumes of structured and unstructured data that are generated every second in today's digital world. This data is so large and complex that traditional data processing applications cannot manage it effectively. The rise of big data has transformed how we understand and analyze information, allowing for deeper insights and new approaches to problem-solving across various fields.
