| AM/FM/GIS is the integrated production of AM/FM and GIS technologies. With the development of AM/FM/GIS technology and its extensive application, AM/FM/GIS has come into a new times, and play an important role in the informationization platform of the enterprises which manage city facilities and establishment.Today, the research on AM/FM/GIS just focuses on some thematic application projects. And there is little study on AM/FM/GIS from the view of how to plot the domain space, how to improve the idea of software design, and how to formalize the description of software and so on. If domain model comes into AM/FM/GIS, it can remove the shortcomings of repeated development etc. which exist in the construction process of AM/FM/GIS application. At the same time, AM/FM/GIS domain model can resolve the contradiction between expanding application demands and slow application construction.Based on the deep analysis of technical characteristics and development situation of AM/FM/GIS, the author points out the defects in the construction of AM/FM/GIS application, such as repeated construction, low reuse ability, and summarizes the entitative character of AM/FM/GIS. The author studies some important domain analysis methods in the world. Because of the virtues of FODA method, the paper researches over AM/FM/GIS domain with the FODA method, tries to plot out the boundary of AM/FM/GIS domain, extracts the domain features of AM/FM/GIS, and gains AM/FM/GIS domain model, including domain structure model, context feature model, operational feature model, representation feature model, information model, and activity model. These models are expressed in UML modeling methods, class description language, and tree view diagram. On the basis of AM/FM/GIS domain model, the author goes deep into AM/FM/GIS domain design and domain realization, and elaborates the construction process of AM/FM/GIS application software on city road light which is based on AM/FM/GIS domain model. |
