A Measuring Method for Achievement of Principles of Sustainable Evolution of Software Architecture

Abstract

The invention discloses a method for measuring the achievement of the principle of sustainable evolution of software architecture, which divides the principle of sustainable evolution into the principle of main body maintenance, the principle of smooth evolution, the principle of independent evolution of modules, the principle of minimizing the size of components, and the principle of stability of external interfaces 6 sub-principles, including the principle of controllable complexity, and measure whether the software architecture achieves the principle of sustainable evolution by measuring the 6 sub-principles. The method selects a metric version and its evolution start version, and the evolution start version evolves into a metric version through an evolution process. Analyze the source code of the two software architecture versions, extract the basic information of the software source code, and then combine the basic information of the architecture extracted from the architecture component diagram to calculate the measurement values ​​of the six sub-principles of the sustainable evolution principle. Finally, assign weights reasonably to each sub-principle, and calculate the weighted average of each sub-principle, which is the measurement result of the sustainable evolution principle, so as to realize the measurement of the sustainable evolution principle of the software architecture.

Description

technical field [0001] The invention relates to a method for measuring the achievement of the principle of sustainable evolution of software architecture, and belongs to the technical field of software architecture measurement and evaluation. Background technique [0002] Software evolution (Software Evolution) refers to the behavior and process of software maintenance during the life cycle of a software system. The ultimate goal of software evolution is to maintain the use value of software. With the rapid development of information technology, the scale and complexity of software continue to expand, and the software evolution process has greater variability. Software architecture is one of the important means to control software complexity, improve software system quality, and support software development and reuse. It is an important research field of software engineering at present. In practical applications, evolution occurs in all aspects of software, and architectur...

Problems solved by technology

[0005] 1. The current research on architectural principles is mainly reflected in the principles of architectural design, including basic principles and key principles. The basic principles include business principles, data principles, application principles, and technical principles. Key principles include single responsibility principle, minimum Knowledge principles, separation of concerns, etc. These principles are proposed for the architecture design stage to guide the architecture design, and have little to do with the architecture evolution process, and there is still a large gap in the research on the architecture evolution process;

[0006] 2. The current measurement of architecture evolution is mainly to extract information and measure a certain version of the software architecture, and lacks the evaluation of the evolution principle of the software architecture in the evolution process
