城市给水管网具有数据量大、地上地下目标之间关系复杂以及要处理图形信息等特点.文中给出了一个基于框架的数据模型,它适应这些特点和用于工程目的,以及对系统进行结构描述和目标组织.同时还分析了整个系统的体系结构,并对各功能模块设计进行了研究. The urban water supply network has the characteristics of large data volume, complex relationship between ground and underground targets, and the need to process graphical information. In the paper, a framework-based data model is given, which adapts to these characteristics and is used for engineering purposes, as well as the structure of the system. Description and target organization. At the same time, the system architecture of the whole system was analyzed and the design of each functional module was studied.
