Research on International Trade Decision Support System Based on Big Data

Since China's accession to the WTO, import and export trade has developed rapidly. With the development of information technology construction, enterprises have accumulated a large amount of business data. This article discusses how to use this data for fast and accurate support decision-making. On the basis of research on data warehouse technology and decision support systems, a decision support system for import and export trade based on data warehouse technology is proposed and implemented. The content includes system architecture, data warehouse model, online analytical processing strategy, and data mining technology. The key technologies of the system are also elaborated. This system realizes the conversion of data held by enterprises into information, and then into knowledge, in order to improve the decision-making ability, efficiency, and accuracy of enterprises. The experiment shows that the system can effectively process and analyze trade data, mine useful information from massive data, and reliably and efficiently store and analyze trade data, helping enterprises formulate marketing plans.
