摘要
1 引言
软件是信息技术的核心,软件的质量则是人们最关心的因素.软件度量作为刻画、评估和预示软件质量的一个必要和重要的方面,在70年代就开始被研究作者所关注.从传统的结构化设计到面向对象理论的产生,一方面不断出现新的软件度量指标,如著名的C&k度量体系,MOOD度量体系;另一方面,对度量指标本身的评价也提出了相应的理论,包括应满足的性质、形式化评估软件度量性质的准则等.随着面向对象技术的广泛应用,传统的度量不再适用于面向对象的某些概念,如类、继承、封装和消息传递,需要有新的度量方法学、度量指标,以更好地刻画、评估和预示面向对象系统的质量.
As object-oriented analysis and design techniques are widely used,the demand on assessing the quality of object-oriented software substantially increases. There are several standards in the measurement of software quality. Internal attribute and external attribute are on different levels. The former describes the structure complexity of the software itself. The latter describes the relationship between software and its environment,which is often related to special applications. In this paper, we propose a criteria suite for object-oriented software measurement based on the ISO9126 quality model to link the internal attribute and the external attribrte.
