面向对象的空间数据库更新机制研究

Research on the Urban Spatial Databases Object-oriented Dynamically Updated Mechanism

针对长期困扰城市空间数据库建设的"更新冲突"问题进行了深入分析,提出了基于对象特征的数据动态更新机制,并完成了系统的设计与开发。实验证明:该系统可以满足城市空间数据库动态更新的需要。

This paper deeply analyzed the problem of ＂Update conflict＂ which long - standing interfered the urban spatial database building. Based on the characteristics of the data object dynamic updating mechanism, it completed the system design and development. Experimental proved that the urban spatial database system can meet the needs of dynamic update.
