Traditional software metrics have the limitations for large-scale software system, so we construct the static structure model for large-scale software by structural mapping and visualization, propose a integrated metrics set based on complex networks parameters according to the perspective of software engineering. The feasibility and validity of the metrics were testified through statistical analyzing the data from a set of software projects; and these experiments show that it can not only uncover the features of software structure such as scale free, small world, but also can get some latent rules about design and structure. These features can be conveniently used by designers and developers to understand the system, control complexity and improve process.
