浅谈软件重用技术及其在GIS软件开发中的应用

Analysis of Software Reuse Technology and Its Use in The Development of Geographic Information Systems

软件重用是重复使用软件资源的过程。软件资源包括程序代码、测试用例、设计文档、设计过程、需要分析文档等等。对于新的软件开发项目而言,它们或者是构成整个目标软件系统的部件, 或者在软件开发过程中发挥某种作用。通过采用软件重用技术能有效地提高软件生产率、降低软件开发成本。本文首先描述软件重用的含义,介绍了目前流行的几种软件重用方法,然后结合GIS软件的开发讨论软件重用技术的应用。

The technology of software reuse refers to the reuse of software resources. It includes the reuse of coding, testing measures, designing document and process, demand analysis document etc. For a new software developing project, such resources form a part of the whole software system or play an important role in the developing period. Software reuse is a powerful means of improving the production rate and reducing the production costs. The paper describes the definition of software reuse and the popular methods of it firstly, then it discusses the related software reuse technologies used in the development of Geographic Information Systems （GISs） .
