Abstract
Data,as a key production factor,has characteristics such as free flow,dynamic combination,cross-domain integration,and value-added utilization.However,it still faces challenges in cross-domain circulation,connecting data silos,and standardized processing.This pa-per proposes a data component abstraction model and encapsulation method from a software system perspective,abstracting data elements into independent,lightweight,and reusable minimum units—data components—possessing addressable,exchangeable,operable,and manageable characteristics.A data component registration and publishing mechanism is designed and implemented,using standardized protocols to support data component discovery and interoperability,providing capabilities such as unified description,encapsulation and publishing,discovery and acquisition,dynamic combination,and trusted interaction,supporting the reliable and efficient cross-domain flow of data elements.Taking a health and elderly care data sharing scenario as an example,a prototype system for data component sharing is designed and implemented for verification.Experimental results show that compared to the traditional microservice model,the cross-domain transmission success rate increases by 13%,the access success rate increases by 11%,the retrieval hit rate increases by 15%,and the scheduling success rate increases by 20%.关键词
