摘要
日志管理对三维空间数据的记录至关重要,可以起到审计和监测的作用。本文利用存储过程和触发器来设计三维空间数据日志的存储并进行管理,同时设置开关适时禁用和启用部分触发器释放资源,不仅能提高Oracle数据库在三维空间数据管理的应用性能,提高开发人员的效率,同时对三维空间数据的管理提供了更好的安全保障。该方法在国家863计划"三维空间数据管理系统与分析组件研发"课题中得以成功运用。
Log management is essential to register the 3D spatial data.It can play the role of audit and monitoring.This paper uses the stored procedure and trigger to design a log system to store and manage the 3D spatial data.It also sets the switches to disable and enable triggers timely to release resources.It is not only an improvement to the Oracle database application performance in the 3D spatial data management and the developer productivity,but also a consolidation to the 3D spatial data management security.This method has been successfully used in the project called ＂research on 3D spatial Data management and analysis components＂ in national 863 program of China.
