摘要
在实践中 ,实现一个GPS/GIS集成系统在技术上是容易的事情 ,但是如何提高软件的开发效率则是需要解决的另一个问题。本文分析GPS/GIS集成软件系统 ,捕获了其共性和变化性 ,将GPS数据通讯进行分解 ,提出基于构件模型的集成系统的实现方案 ,该实现方案便于控制系统的变化性 。
It practically is straightforward to achieve a GPS/GIS integrated system technically. But how to improve the efficiency of software development is another problem to be solved. Generality and variation existing in the system is captured through analyzing GPS/GIS integrated system. Based on the analysis results, the GPS data communication is decomposed, and the component-based integration implementation is raised. The implementation is more flexible and more convenient to control the change of system, and supports reuse of the software.
