摘要
分建共享是空间数据在逻辑上集中式管理、物理上分布式存储,各专业部门各自管理和维护各自的数据,通过Web服务调用的方式实现异构空间数据库的互操作,进而实现物理上分布式存储的数据共享方式。分建共享方式为用户提供一种数据同步更新、数据安全共享、异构数据互操作的技术解决方案。本文主要阐述"分建共享"的空间数据共享机制在数据存储、数据服务、服务调度、网络环境4部分建设过程中采用的关键技术以及实现方式。并通过具体应用项目来论证"分建共享"的空间数据共享机制在空间数据共享、协同办公方面的优势。
The distributed spatial data sharing mode is spatial data logically centralized management and physically distributed storage and the professional sector of their management and maintenance of the respective data, by way of web service call realize the interoperability of heterogeneous spatial databases, so as to realize the physically distributed storage of data sharing mode. The technology solution for data synchronization, data security sharing, and heterogeneous data interoperability is provided by the user with a sharing mode. This paper mainly expounds the key technologies in the construction and sharing of spatial data sharing mechanism is adopted in data storage, data service, service scheduling, network environment four parts construction process and implementation. And through the specific application of the project to demonstrate the sharing mechanism of spatial data sharing, the advantages of spatial data sharing and collaboration office.
