In recent years, big data has emerged as one of the prominent buzzwords in business and management.In spite of the mounting body of research on big data across the social science disciplines, scholars have offered little synthesis on the current state of knowledge. In this paper, we developed an integrated framework to link the multiple streams of research in fields of organisation, operations, marketing, information management and other relevant areas. Our analysis demonstrates how both structured and unstructured big data has been harnessed to inform organisational decisions and improve firm competitiveness. The review also indicates that big data has also unleashed novel challenges in term of security and privacy of personal data. In light of these, the study identifies and outlines the implications and directions for future research.
