Research on Freight Big Data Application Based on Railway Data Service Platform

According to the current status of railway freight data assets, the overall architecture of railway freight big data application based on the railway data service platform is proposed, including the processing flows of data acquisition and access, assets directory construction, data modeling and management, data storage and analysis, etc. Besides, the key technologies, e.g. the construction of data model based on source and paradigm approaches, Greenplum-based Ad Hoc queries of data, freight-specific data models are also studied. Based on the data of some existing freight business systems and the distributed computing architecture of the railway data service platform, this paper conducted Ad Hoc queries case analysis and the application practice of freight-specific algorithm library, thus verified the feasibility of key technologies, and provided data and technical support for the comprehensive analysis and mining application of freight big data.
