Big data in retail refers to the vast volume of structured and unstructured data collected from various sources, such as customer transactions, social media, online browsing, and inventory tracking. Leveraging big data allows retailers to gain insights into customer behavior, optimize operations, and improve decision-making.

1. What is Big Data?
