Abstract Research purposes:The quality of railway engineering master data is related to the quality of the results of the overall railway engineering field informatization and intelligent construction, and it is the data base of the railway engineering informatization field. This paper analyzes the characteristics of railway engineering from the perspective of ontology, identifies the core master data classification in the field of railway engineering, focuses on analyzing the business relationship between data entities, and proposes the technical architecture, data structure and data service realization technical plan and path of the railway engineering master data management system, and at the same time, the management mechanism and method of railway engineering master data are proposed from a management perspective, which lays the foundation for the improvement of railway engineering informatization management level and the implementation of intelligent construction.
Research conclusions:(1) Apply ontology to identify the core data entities of master data in the railway engineering field. (2) Apply ontology to analyze the business relationship between master data in railway engineering, and analyze the composition and correlation of master data from the macro-management and micro-execution levels, and distinguish between sensitive entities and steady-state entities. (3) The technical architecture, data architecture, functional architecture and implementation route of a flexible railway engineering master data management system are proposed to provides technical mean for realizing the flexible and changeable management of railway engineering master data. (4) This paper puts forward the railway engineering master data management mechanism, which provides reference ideas for the development of railway engineering master data management from four aspects: management methods, process audit, data visualization and special team maintenance.

Key words： ontology railway engineering master data management sensitive entity steady state entity master data management system
