Retail data is an academic concept and research domain focused on the systematic collection, organization, and analysis of information generated throughout the retail value chain, from operations to customer engagement. It investigates empirical patterns in sales, inventory management, supply chain logistics, customer behavior, and market trends, utilizing data characterized by its volume, velocity, and variety derived from diverse retail touchpoints such as point-of-sale systems, e-commerce platforms, and customer relationship management systems. This concept is significant for developing theoretical frameworks and empirical insights into consumer science, operational efficiency, and strategic decision-making within the retail sector.
