摘要: 采用元数据驱动方法,研究分布式数据资源管理,实现数据的统一组织,提供高效数据共享服务。在对数据进行分类分析基础上,基于元数据定义和管理,开展分布式数据管理的数据检索和缓存。突破分布式数据资源管理关键技术瓶颈,构建分布式资源全局目录,实现目录服务,进行高效传输的数据缓存管理,减少处理、采集、分发的延时。提供基于多副本的动态自适应数据调度方案,解决分布式数据资源管理的数据选择和动态变化问题。
关键词: 分布式数据资源管理, 元数据, 全局目录, 数据缓存, 自适应数据调度
Abstract: By metadata driven method, the distributed data resource management technology is studied. The data unified organization is implemented. The high effective data sharing services are provided. After analyzing and classifying data, based on metadata definition and management, the data is indexed and cached in distributed data management. The key technologies are studied, including the distributed resource global directory construction for directory service, the high speed transportation in data cache management for reducing delay of dealing, collecting, and dispatching data. The dynamical and adaptive data scheduling way based on multi-backup is provided for resolving the data selection and dynamical refresh in distributed data resource management.
Key words: distributed data resource management, metadata, global directory, data cache, adaptive data scheduling
