Abstract

The invention relates to a software system structure recovery method based on a functional structure, belongs to the technical field of software system recovery, and solves the problem that a software system structure recovered by an existing mode is difficult to understand. The method comprises the following steps: constructing functional structure knowledge, wherein each function comprises a parent function and / or a child function and a function related class, and the lowest-layer function in the functions comprises function related classes; respectively mapping the parent function, the child function and the lowest layer function into a parent component, a child component and a leaf component, and dividing the function related class into the corresponding leaf component; removing classes included in the component from all classes to obtain unrecovered classes; calculating the correlation between each unrecovered class and each leaf component, and dividing the class with the correlation exceeding a correlation threshold value into the leaf component with the highest correlation; traversing all unrecovered classes repeatedly, and obtaining updated components; if all the classes are recovered, recovering the software system structure of the software based on the updated components.

Description

technical field [0001] The invention relates to the technical field of software system restoration, in particular to a method for restoring a software system structure based on a functional structure. Background technique [0002] Software architecture is regarded by relevant scholars and practitioners as an important basis for software development and evolution, but there are three problems in the process of software development and evolution: First, in the context of agile development, practitioners believe that "workable The software is better than the broad document”, they simply designed a software architecture without sufficient verification, or did not design the corresponding software architecture, and began to realize the software system only through the requirements provided by users. Second, even if the software architecture is designed and fully verified, there are problems in the development process that do not follow the designed software architecture, resultin...
