摘要
在许多数据库应用软件开发的过程中,存在数据镜像、汇总、备份等实时性的数据处理需求。本文在分析污染源监控系统主动数据处理需求和监控设备模块化要求的基础上,利用主动数据库和面向对象技术,设计了面向对象的污染源主动监控系统。介绍了面向主动对象数据库技术原理,阐述了主动监控系统的实现机制,分析了面向设备的建模方案,并给出了其具体的应用。
In the development process of many database application software, there exists real-time data processing requirement for data mirroring, data collect, data backup, and so on. Basing on analysis of initiative data processing requirement in the pollution resource controlling system and the modularization for monitoring devices, using active database and object-oriented technology, this paper designs the pollution control system based on active object-oriented database. It introduces the principle of active database and object-oriented technology, explains the implementation of active controlling system, analyses device-oriented modeling project and gives the application in details.
