[0018] 1. Class dependency diagram of object-oriented system

[0019] In a real software system, for a class C of an object-oriented system, where A = {A 1 ,A 2 ,...,A m} is the attribute set of class C, M={M 1 , M 2 ,...,M n} is the method set of class C, then there are three kinds of dependencies between the attribute set and method set of class C: the dependency between attributes and attributes; the dependency between methods and methods; the dependency between methods and attributes dep...

Abstract

The invention discloses a method for measuring class cohesion orientated to an object software system. According to the method, a small world model of a complicated network and the structural entropy theory are combined into the method, namely the larger the colony coefficient is, the smaller the average distance is, the more even the degree distribution is and the larger the cohesion is. Meanwhile, in terms of subgraphs which are not communicated, the product of the proportions of the numbers of nodes of the subgraphs in the overall number of nodes of the subgraphs is used for calculating the cohesion of the whole network. By means of the method, the cohesion of the network between attributes, the cohesion of the network between methods and the cohesions of the network between the methods and the attributes in the class oriented to the object software system are analyzed respectively. Finally, according to the condition of the software system, the weights of the three relations are set so as to calculate the cohesion of the class. Compared with the prior art, the method has the better measuring effect and the practical application value.

Description

technical field [0001] The invention relates to a software measurement method, in particular to a method for measuring the cohesion degree of a class by using a small-world model of a complex network and structural entropy, and belongs to the intersection field of software engineering technology and complex networks. Background technique [0002] The goal of software engineering is to develop new technologies and tools to improve software quality, make it more stable and easier to maintain. To evaluate and improve software quality during development, program developers and managers use metrics that estimate properties of different software, such as cohesion, coupling, and complexity. Cohesion refers to the connection strength between components inside a module, and is a major indicator of software quality. The higher the cohesion, the easier it is to understand, modify and maintain. However, cohesion itself is a subjective and informal concept, and it is difficult for peopl...
