基于客户/服务器结构的空间数据分布式处理研究

Study on Distributed Processing of Spatial Dais Based on Client Server Architecture

该文简要分析了当前空间数据的分布式处理状况，以面向跨区域的地籍管理应用为例，利用空间与非空间数据库的集成和基于客户／服务器体系结构的分布式系统技术，设计了空间数据的分布式处理的方案。阐述了具有空间分布特征的地籍数据库的分布式设计，详细介绍了其中的数据分布与分布透明、空间数据库与非空间的关系数据库集成、分布式查询处理及数据一致等内容。

The current status of distributed processing of the spatial data is primarily summarized in this paper. With integrating of the spatial data and non-spatial data and the technique of distributed system based on Client/Server architecture, a project is carried out for the spatial data distributed processing. It expounds the distributed design of cadastral database with spatial distribution characteristics. The transparent distribution,the integration of the spatial database and relational database,distributed query processing,data update in multiple places,data consistency are presented in detail.
