Office GIS中图文控制流与数据流的rn集成设计和表达

摘要

通过分析传统软件工程设计方法在城市规划管理类的图文办公信息系统设计应用方面存在的问题及不足，在分析借鉴控制流与数据流集成表达的基础上，针对城市规划管理图文办公信息系统中图形与文本集成管理及处理的具体特点，提出了基于层次结构的图文控制流与数据流集成设计及表达的方法.该方法不仅在常州市规划国土管理局图文办公信息系统的设计与集成中得到了成功应用，而且极大地提高了系统的设计水平及开发效率，其应用效果证明了该方法的有效性和实用性.%GIS(Geographical Information System) has been used more and more widely in various fields. One of the most important application is that GIS is integrated with OIS(Office Information System) to form the so-called Office GIS. Data flow diagram and control flow diagram are two approaches used in traditional software engineering, but they are not well suited to Office GIS. Base on the integrated expression of control flow and data flow, a new approach is proposed in this paper, which integrates data flow and control flow considering both spatial and attribute data in Office GIS. The quality and efficiency of system design are greatly improved by applying the approach in system designing of Office GIS, which proves that the approach is feasible and effective.
