Oracle+ArcSDE模式下空间数据库用户监控技术研究

Research on the User Monitoring Technology in Oracle Spatial Database with ArcSDE

针对Oracle+ArcSDE模式下空间数据库的特点,分析了Oracle系统表及ArcSDE系统表间的关联性;并基于这种关联性,提出了采用Oracle触发器机制的用户监测技术;最后设计并实现了用户监控系统。

According to the characteristics of Oracle spatial database with ArcSDE,this paper analyzed the correlation between the system’s tables of Oracle and ArcSDE.Based on the correlation,it presented the user monitoring technology with Oracle trigger.At last it designed and implemented a user monitoring system based on this technology.
