【摘要】 有效地定位、访问、浏览数据是异构广域网络中急需解决的问题,数据网格技术是解决此问题的有效手段之一。通过运用虚拟化的元数据模型,并在其基础上提出了单一的数据访问接口,同时运用单一的数据访问接口构建了元数据目录服务系统,最后在地震减灾仿真网格系统中应用该设计思想实现了地震数据的有效管理。更多还原

【Abstract】 Locating,accessing,retrieving data efficiently is a main problem needed to be solved in WAN.Data Grid is an efficient way to solve the problem.The virtual Mete data model was used to put forward the unique data accessing interface.The unique data accessing interface was used to build the Mete data Directory Service.Finally the design concept was used to build the data management in Earthquake Disaster Alleviation Simulation Grid System.The efficient management on data resource was implemented.更多还原
