摘要
针对基于关系型数据库的地理信息传播模型在互联网虚拟计算环境下的不足,提出了一种基于文档数据库的全栈式地理信息传播模型。该模型以多粒度地理特征的映射规约分析计算和文档数据库的多版本并发控制为框架,用统一的内建域指定语言作为传播媒介描述载体,结合数据的运行时元编程和地理服务的REST风格部署,实现地理空间数据的动态开放式传播,证明非结构化地理空间数据的传播模型能满足逻辑语义和物理存储双重易扩展性。
Based on document-oriented database,this paper presented a full-stack propagation model of geospatial data that make up the the deficiencies of relational database-based geographical information dissemination model. Mapreduce analysis of multi-granularity geographical features and document based multi-version concurrency control provided a basic framework for the model . With an unified built-in domain description of the specified language as a carrier of the media,the model combined with data on run-time meta-programming and REST-style deployment. At last it reached a target of the dynamic open geospatial data dissemination and met the needs of accessible logical semantics and scalable mass storage.
