一种基于剖分的空间数据存储调度服务模型

摘要

With the spatial data applications to the depth and breadth of expansion, spatial data exist for speed, efficiency and other problems in the organization,storage, update, applications and other aspects. In view of the above problems, based on global subdivision organization theory, combined with the client oriented aggregation service that G/S mode, studied and proposed a space subdivision data storage scheduling service model,and presented the model architecture, data access process,designs the address coding structure and resolution process,forming effective mechanism of space subdivision data organization and management,according to the needs of integration, fast scheduling with data distributed storage and client information aggregatioa Finally realized and verified the prototype system, it has certain theory significance and the application value.%随着空间数据应用领域深度和广度的扩展,空间数据在组织、存储、更新、应用等方面存在速度、效率等难题.针对上述问题,基于地球剖分组织理论,结合面向客户端聚合服务的G/S模式架构,研究并提出一种空间剖分数据存储调度服务模型.给出了该模型体系架构、数据访问流程,设计了模型的地址编码结构及地址解析过程,形成了一种有效的“数据分散存储,客户端信息汇聚”的空间剖分数据组织管理、按需整合、快捷调度的机制,实现并验证了服务原型系统,其具有一定的理论意义和应用价值.
