【摘要】 软件工程是指导软件开发的科学，它是软件业规模化生产的关键。目前，地理信息系统(GIS)已经在各行各业得到了广泛应用，已经成为一项关系到国民经济、国防建设的产业，这要求我们研发自主版权、功能强大、运行稳定的GIS软件。既然是软件，又是有规模的软件，就必须针对它进行软件开发方法的研究。 本文从思想上、管理上阐述了软件工程的内涵，结合Linux操作系统的成长提出W/G模式的GIS软件工程技术。文章讨论了W/G模式的研究内容及内容构成，由总体目标确定、内核设计、功能部件实现三部分构成。文章给出了总体目标图，分析了三种内核设计技术后，采用面向对象技术进行了部件化的系统内核设计。文章详细描述了内核的构成部件，介绍了内核面向对象数据模型设计，给出了具体的内核部件实现。更多还原

【Abstract】 SE(Software Engineering) is a science guiding the development of software, it is the key to develop software in a big way. Today GIS has been used every walk of life, it is a industry concerned with National Economy and National Defence. This condition asks us to develop GIS software independent, it has powerful ructions and run stably. As being software and powerful software, we must argue its developing method.This paper discussed the meaning of SE in Thinking method and management, W/G SE for GIS was drawn after describing the growing of Linux OS. It discussed the research content of W/G SE and the components of confirming Whole-role, designing System-core, realizing the part-components. The diagram of Whole-Role was given. Three methods of core designing were introduced, then the author designed the system core composed of components with the help of Object Orient technology. The diagram of core’s parts was shown in datail. The object-orient data modals were written detailedly togther with the realizing of components of the core.更多还原
