Attainable measurement method for sustainable evolution principle of software architecture

Abstract

The invention discloses an attainable measurement method for a sustainable evolution principle of software architecture. The method divides the sustainable evolution principle into six sub-principles,including a main body maintenance principle, a smooth evolution principle, a module independent evolution principle, a component scale minimization principle, an external interface stability principle, a complexity controllable principle and the like, six sub-principles are measured to realize a purpose of measuring whether the software architecture achieves the sustainable evolution principle ornot. The method selects a measurement version and an evolution starting version thereof, wherein the evolution starting version is evolved into a measurement version through an evolution process. Thesource codes of two software architecture versions are analyzed, and the basic information of the software source codes is extracted and is combined with architecture basic information extracted froman architecture component diagram to calculate six sub-principle measurement values of the sustainable evolution principle. Finally, weight is reasonably distributed to each sub-principle, the weighted average, i.e., the measurement result of the sustainable evolution principle, of each sub-principle is calculated, and therefore, the measurement of the sustainable evolution principle of the software architecture is realized.

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
