Functional Structure of Urban Water Supply Network Based on GIS

The functional requirements of water supply network based on GIS are introduced. The application logic structure of water supply network based on GIS chooses three-tier/N-tier architecture. The system is divided into six subsystems. Among them, the analysis subsystem, the aided design subsystem, the installation and maintenance management subsystem and the customer service subsystem serve data management subsystem. The system management subsystem is the control center of other subsystems. The urban network MIS stated in this paper has been implemented successfully in some cities of China.
