摘要
以实现领域科学数据共享为目的,提出一种基于虚拟数据空间的共享模型.通过探讨模型中的主体、数据、服务与空间四要素,研究基于逻辑实体和逻辑实体集的领域科学数据聚合.针对领域内的各类应用主题以及个体的需求,将分散的领域科学数据聚集成与服务相关的虚拟数据空间,利用主体对服务的共享来实现数据的共享.最后,以石油领域油气井科研数据管理平台为例,阐述油气井科研数据共享的实现过程.实际应用表明,虚拟数据空间共享模型对于领域科学数据共享是高效可行的,并为数据密集型应用、领域内的服务开发与部署提供了良好的支持.
To realize domain-specific science data sharing, a kind of data sharing model based on virtual data space is proposed in this paper. Discussing principals, data, service and space elements in this model,the research focused on domain-specific science data re- sources aggregation based on the logical entity and logical entity set. Towards various application theme and individual demand,the scattered domain-specific science data gathered to data space related service, by means of the sharing service to realize data sharing. Finally, Oil and gas well research data sharing platform as an example, the realization of virtual data space model towards oil and gas well research data sharing is described. The practice indicates that the virtual data space model to realize science data sharing is effi- cient and feasible, and provide good support for data-intensive application and service deployment.
