Given the global significance of the tourism sector, its constant growth, and the influence of new technologies and digitalization, a literature review was conducted to analyze previous studies related to the use of Big Data in the tourism industry, incorporating examples of companies/brands on the Big Data management. This chapter aims to provide insights into the role of Big Data in the tourism sector and the leverage of Big Data by stakeholders on digital technologies to enhance smart tourism. The findings offer a summary of the primary uses of Big Data in the tourist industry, such as enhancing visitor experiences, streamlining resource allocation, and enhancing decision-making procedures. The results also illustrate how Big Data management and implementation can facilitate more adequate tourist practices, leading to more effective and customized offerings. This analysis also points out the main issues to Big Data implementation such as data integration and technology barriers. This study brings a raft of implications, offering valuable insights for tourism industry agents on how to harness the potential of Big Data. Furthermore, recommendations are proposed to address the identified challenges, including future research directions to further explore the impact of Big Data on the tourism sector.
