    • A geographically distributed storage system for managing the distribution of data elements wherein requests for given data elements incur a geographic inertia. The geographically distributed storage system comprises geographically distributed sites, each comprises a site storage unit for locally storing a portion of a globally coherent distributed database that includes the data elements and a local access point for receiving requests relating to ones of the data elements. The and geographically distributed storage system comprises a data management module for forwarding at least one requested data element to the local access point at a first of the geographically distributed sites from which the request is received and storing the at least one requested data element at the first site, thereby to provide local accessibility to the data element for future requests from the first site while maintaining the globally coherency of the distributed database.
    • 一种地理分布式存储系统,用于管理数据元素的分布,其中给定数据元素的请求引起地理惯性。 地理分布式存储系统包括地理上分布的站点,每个站点包括站点存储单元,用于本地存储包括数据元素的全局一致性分布式数据库的一部分,以及用于接收与数据元素之一相关的请求的本地接入点。 地理分布式存储系统包括数据管理模块,用于在接收到请求的第一个地理分布站点处将至少一个所请求的数据元素转发到本地接入点,并将第一个请求的数据元素存储在第一个 从而为维护分布式数据库的全局一致性提供来自第一站点的未来请求的数据元素的本地可访问性。
