Problems solved by technology

After multiple versions, the code has changed a lot from the original code, and it cannot correspond to the original model. At this time, if the model is needed to complete the relevant work, you will encounter the inconsistency between the model and the code
This inconsistency will cause the model to expire, and a series of software development activities related to the model will not be able to proceed normally.

Embodiment Construction

[0040] In the specific implementation of the software model synchronization method based on code change described in the present invention, the existing software model and the software code corresponding to the software model are first required, and different versions of the same code unit can be managed through the version control system. The present invention analyzes different software models according to the rule set, and can adopt code retrieval technology and combine heuristic information to establish corresponding correspondence between elements in the model and elements in the code. Compare the codes of different versions, filter out more important changes, decide how to modify, delete and add models according to the applicable rule set of the software model, and finally update the model.

[0041] The specific implementation process of the software model synchronization method based on code changes described in the present invention is as follows: figure 1 shown.

Abstract

The invention provides a software model synchronization method based on code modification. By means of the method, non-substantial modification, non-essential modification and non-correlation modification codes are filtered out from changed codes, and modification codes relevant to a software model are obtained. The software model is matched with the relevant modification codes, a corresponding relation between elements in the model and elements in the codes is built, the obtained code modification information and the corresponding relation between the elements in the model and the elements in the codes are translated into updating operation, a new model is generated, and model synchronization is achieved. The software model synchronization method can be integrated in a code version management system, automatic or semi-automatic updating of the software model can be conducted by pre-defining rules, and consistency of the software model and the codes is guaranteed.

Description

technical field [0001] The invention relates to a method for synchronizing outdated software models and new codes, and belongs to the interdisciplinary technical fields of software engineering and model-driven engineering. Background technique [0002] Model-driven engineering takes the model as the main product, and attempts to clarify the content of software development through the establishment of models, which is an important topic in the development of software engineering in recent years. The model is expressed in a modeling language, which can describe software but is higher than software. It is an intermediate product that describes design and guides software development. [0003] The standard software development process includes the steps of requirement analysis, model design, code writing, and test deployment. Among them, model design not only undertakes various elements in demand analysis, but also serves as the benchmark for subsequent activities such as writin...
