Abstract: In order to solve the problems of long publishing cycle of paper railway passenger traffic fare-mileage table and schematic diagram of national railway passenger traffic operating stations and the inconveniences for users in using those paper table and schematic diagram, a data management system for railway passenger traffic fare and mileage table is developed. Based on micro service technology and adopting a mixed mode of C/S and B/S application, this system realizes centralized data management and maintenance of railway passenger traffic fare-mileage table and schematic diagram of national railway passenger traffic operating stations and can provide convenient customized data query functions for related personnel, as well as railway passenger traffic fare-mileage table data sharing services for other railway application systems. The system constructs the data model of national passenger railway network with trunk branch line two-level tree structure, and uses the vector graphics technology for drawing the schematic diagram of national railway passenger traffic operating stations. In addition, this system provides consistency check on the table and the schematic diagram data as well as version management of the data, which can ensure the integrity of the data and the traceability of data update process to achieve orderly and controllable release of the data. The application of the system standardizes data management and maintenance of passenger traffic fare-mileage table and facilitates accurate use of the data by the end users, improves the work quality and efficiency of related railway passenger traffic business.
