The research of the core inherited tree in softerware network

This paper analyses network software metrics based on the theory of the network software in order to reveal the object-oriented software system structure characteristics, and the structure and function of the internal connection. It is found that the nodes in software network are inherited tree such units, and limited gather together only in the tree. According to statistics, it can be seen that the number of nodes in core inherited tree is more than 20% the number of nodes in whole software network, which constitute the core structure of the network. Through the analysis of the distribution of the core inherited tree, the higher cohesion of associated side of the core inherited tree is caused by high cohesion within the node of inheriting tree.
