Research on the Architecture of Urban Emergency System Based on GIS

摘要

Architecture technology is development model based on some sort of application, offers a wide range of software reuse to provide a unified software development kit for developers and model architecture. First, research the infrastructure consists of Core layer, organization layer, communication layer, executive layer and collaborative layer; Then, research the data structure that business layer department building and maintaining independently and shared with each section based on the spatial data structure of geographic information. Finally, research the MVC software architecture, describing the division of labor and cooperation among the Model, View and Controller. Application of this results, not only significantly improve the development efficiency, and the system has more advantage like clear structure, stable performance, easy maintenance and easy to transplant, etc.
