面向城市规划的空间数据库动态更新模型研究

本文针对长期困扰城市空间数据库建设的"更新冲突"和"更新速度慢"问题进行了深入分析,在研究、借鉴前人的时空数据更新方法的基础上,根据城市规划空间数据实际生产特点,将时间维引入城市空间数据库,按照事件驱动思想,提出了基于对象特征的数据动态更新模型和动态更新机制,解决数据管理与数据生产之间数据并发性更新需要,并能实现数据库不同历史时期版本输出问题。按照此数据动态更新模型,作者在内外业系统上进行开发实现,并通过生产实验验证,分析应用效果。

The research of dynamically updated spatial database model for urban planning

This paper gives an in-depth analysis of two outstanding issues in urban spatial database construction: "update conflict" and "slow update". With reference of previous research on spatio-temporal data updating methods and the event-driven approach, this study introduces a dynamic data updating model by adding time dimension to the urban spatial database. This model addresses the concurrent data updating issues between data administration and data generation, as well as data versioning issues. The authors utilize this model in both internal and external systems, and test it in a production environment. The application results are discussed.
