Abstract: The intercommunication of scientific research data within the tobacco industry is not as convenient as it is expected currently due to the lack of unified standards, therefore a standard system for big data of tobacco scientific research was outlined by analyzing the standards of big data relevant to scientific research at home and abroad and integrating with the characteristics of tobacco research activities and research data resources. The system divided standards and norms into four categories: basic standards, technical standards, business standards and management methods. Guided by the standard system framework, the key standards and the data element standards in business fields of tobacco industry were drafted to provide a base for scientific research data collection and analysis. The configuration of this system effectively promotes the orderly specification and efficient use of data resources and provides a data support for the technological innovation in tobacco industry.
