Application of Design Patterns in Process of Large-Scale Software Evolving

Abstract

To search for the Design Patterns’ influence on the software, the paper abstracts the feature models of 9 kinds of classic exiting design patterns among the 23 kinds and describes the features with algorithm language. Meanwhile, searching for the specific structure features in the network, the paper designs 9 matching algorithms of the 9 kinds design patterns mentioned above to research on the structure of the design patterns in the software network. At last, the paper analyzes the evolving trends of the software scale and the application frequency of the 9 kinds of design patterns as the software evolves, and search for the rules how these design patterns are applied into 4 kinds of typical software

A Bridge Role Metric Model for Nodes in Software Networks

“…Furthermore, other studies have been analyzed in software systems, and subsequently, the methodology of dependability in software networks based on three dimensions of structure has been discussed, and the structural stability in software is analyzed on dimension of composition. Because of the reusability of design patterns in object-oriented software systems, the design patterns are regarded as a typical structure that has more effect on the whole [27] , [28] . [29] has studied nine large object-oriented software networks, recovering that graphs associated with these software networks are self-similar.…”
