[0019] 1. Network coupling analysis of object-oriented software system

[0020] The degree of connectivity between classes in a software system network reflects the importance of classes in the network to a certain extent, and has always been used as an important indicator for judging the complexity of the network structure. However, the connectivity of a class cannot fully reflect the influence of the clas...

Abstract

The invention discloses an inter-class coupling measurement method for an object-oriented software system. In the object-oriented software system, coupling is a measurement standard for the correlation degree between all classes of software. In order to well measure the coupling between the classes in the software system, firstly, the object-oriented software system is represented in a formalized mode, and the coupling relations between all the classes in the software system are analyzed through the affection degree so as to find the influences of the classes in the system; secondly, the Lorenz curve and the concept of the Gini coefficient are combined and popularized to a complex network, and the heterogeneity of the network is analyzed; thirdly, the software system coupling measurement method based on the complex network is put forward, and analysis is conducted through abstract examples.

Description

technical field [0001] The present invention relates to a software measurement method, specifically extending the concepts of sweep, Lorenz curve and Gini coefficient to complex networks, and proposing a measurement method for coupling degree of software systems based on complex networks, which is carried out with abstract examples analyze. It belongs to the intersection field of software engineering technology and complex network. Background technique [0002] In software design, the degree of coupling and cohesion are usually used as the standard to measure the degree of module independence. One criterion for dividing modules is high cohesion and low coupling. Coupling refers to the closeness of the connection between modules. The coupling degree between modules refers to the dependency relationship between modules, including control relationship, call relationship, and data transfer relationship. The more links between modules, the stronger their coupling, and the les...
