对分布式关系与空间混合数据库特征进行了分析。使用基于惰性副本控制协议的关系数据同步技术和基于“双向同步复制”的SDE(Spatial Data Engine)空间数据库同步技术,设计实现了分布式关系与空间混合数据库同步组件。在此基础上,结合国内大中型煤矿网络特点,提出并设计了基于分布式数据库的煤矿瓦斯灾害预警软件体系结构,并在MicrosoftC#2.0和ESRI ArcEngine平台中实现。
The characteristics of distributed relational and spatial hybrid database are analyzed. Using the relational data synchronization technology based on the inert copy control protocol and Spatial Data Engine (SDE) spatial database synchronization technology based on “Bidirectional Synchronous Replication ”, a distributed relational and space hybrid database synchronization component is designed and implemented. On this basis, combined with the characteristics of domestic large and medium-sized coal mine network, this paper proposes and designs a software system for early warning of coal mine gas disasters based on distributed database. It is implemented in MicrosoftC # 2.0 and ESRI ArcEngine platform.
