基于构件库管理系统的构件复用度度量模型

构件概念及其理论的发展始终以软件复用为切入点,只有被最大可能地复用,构件才有其存在的意义和经济价值。如何用一种较为精确的、基于实践应用的方法来评价构件的复用度,关系到构件质量的提高和构件库的有效性。该文介绍了构件复用的概念,并结合构件库管理系统,提供了一个对构件复用度的度量模型,分析了度量结果对构件库的反馈作用,能够对构件库管理系统的设计与实现提供参考。

Metrics Model of Component Reuse Degree Based on Component-Base Management System

The concep t and theory of component always lay emphasis on software reuse.A component ma y achieve its meaning of existing and economic value only after it is reused as possible.It is referred to the improvement of components and efficiency of a c omponent -base that how to evaluate the metrics degree of components with an ac curate and practice-based method.This paper introduces the concept of compone nt reuse,provides a metrics model for component reuse degree and analyses its effect on component-base.It can also help the design and implementation of a component-base.
