基于构件的地理信息系统应用软件开发模型研究

The Development Model of GIS Application Software Based on the Component Software

构件技术是软件复用的主要发展方向之一，本文在介绍构件及其相关技术的基础上，提出了基于可重用构件的地理信息系统应用软件的体系结构和开发模型，并对其中的基本技术问题作了讨论，解决了在GIS应用软件系统的开发中如何采用构件技术的问题。

The component software is one of the main technology of software reusing． This paper first introduces the concept of component and its kinds, then presents the development model of the application software of geographic information system based on the resued component software, and describes the main technologic problem in the model． This paper has solved the problem of how to use component software technology in the development of application software of geographic information system．
