After the establishment of several free trade zones and cross-border e-commerce comprehensive pilot zones along the coast of China, the volume of China's international trade has grown rapidly, but at the same time, the trade situation has become increasingly complex. In order to develop the international trade business better, the scientific formulation and timely adjustment of trade policy need to be carried out. Policy making and adjustment need to be based on the integration and sharing of massive data. In order to solve the problem that the performance of traditional heterogeneous data integration and sharing system is insufficient, a coastal international trade heterogeneous data integration and sharing system based on middleware and XML is designed. This system introduces the key technologies of system design, which are middleware and XML. Then a four-tier architecture based on middleware and XML is designed, and then the heterogeneous data integration module is analyzed, including mediator, wrapper and Web Services management. Finally, the system is implemented and tested. The results show that the system is superior to three traditional heterogeneous data integration and sharing systems in four aspects: query speed, accuracy, integration and whether it supports data structure, which proves that the performance of the system is stronger.
