Although a large body of research in software metrics has benn focused on procedural of object-oriented software, there is no software metric for aspect-oriented software until now. In this paper, we propose some metrics for aspect-oriented In this paper, we propose some metrics for aspect-iruebted siftwarem which are specifically designed to quantify the in-formation flows in an aspect-oriented program. We define these metrics based on a dependence model for aspect-oriented soft ware which consists of a group of depentence graphs each can be used to explicitly represent various dependence rela-tions at different levels of an aspect-oriented program. The proposed metrics can be used to measure the complexity of an aspect-oriented program frm various different.
