摘要
在水库洪水调度系统等数据库应用软件的开发过程中,存在数据镜像、汇总、备份等实时主动的数据处理需求。在分析水库洪水调度系统主动数据处理需求的基础上,通过应用基于触发器的主动数据库技术,实现了遥测数据镜像等主动数据处理功能,增强了水库洪水调度系统数据库的主动性与实时性。
In the development of the reservoir flood control system software, there are many requirements about real active data processing, such as data mirroring, summation and coping. However, the traditional data dealing methods in the C/S program design are asynchronous and passive. Based on the analysis of the active data processing requirements, the database trigger was applied to the reservoir flood control system. Thus, the active data processing functions such as remote data mirroring is realized to improve the real-time and active functions of the reservoir flood control system.
