摘要
为便于动车组信息资源的交换和共享,对动车组业务提供准确可靠的数据支持,在对现有多个动车组相关信息系统进行充分调研的基础上,编制了动车组数据资源目录;明确动车组数据资源的业务域划分,根据结构化与非结构化数据的特点,对分散在多个系统中的动车组数据进行整理和采集,依据相关标准完成动车组主数据的数据元定义、代码集统一编码和元数据规范描述,可为相关单位和人员提供便利的可共享动车组数据资源的参考指南,有利于促进动车组信息化系统的集成,提升动车组数据资产价值。
To facilitate data interchange and sharing of EMU data resource and provide accurate and reliable data for EMU business,the EMU data catalog is compilated through making a thorough investigation on the data in several existing EMU information systems.The business domain of EMU data resource are divided,the data from those system are sorted and collected according to the characteristics of structured and unstructured data.Data elements and metadata are defined and unified code sets are established in compliance with relevant standards,encodes according to national standards,and completes EMU data resource catalog.The EMU data resource catalog can serve as a convenient reference guide to shareable EMU data resources for related units and personnel,which is conducive to promoting the integration of EMU information systems and enhancing the value of EMU data assets.
