Abstract

The invention relates to a modelling method and system for an object changing model on the basis of tense. The method comprises the following steps that: defining at least one of software requirement, design, models, components, software products, development departments, development personnel and changed software development elements which change along with time into a tense entity; establishing database modes which include a table, a view, a storage process and the like and correspond to the tense entity and tense entity connection, wherein the above database modes at least comprise a time attribute field, the internal dependence field of the tense entity and the external dependence field of the tense entity; and accessing above all database modes, establishing an MTDG (Multilayer Temporal Dependency Graph), obtaining required dependence analysis which relates to the internal side and the external side of the tense entity according to the above MTDG, and obtaining the MTDG which contains changes. The method is favorable for timely finding an influence on other modules or a whole software system after certain parts in a software system are changed (such as version upgrading and version change) in software configuration management, software development and maintenance cost is lowered, and software configuration efficiency is improved.

Description

technical field [0001] The present invention relates to software engineering and database technology, in particular to a method and system for building a temporal object change model for software configuration management in software configuration and management. Background technique [0002] Change impact analysis is another key technology of software configuration management. Change impact analysis is an important means to ensure software quality, and can reduce software maintenance and testing costs, because only the affected software objects (models, components or other software objects) need to be maintained and tested. Firstly, analyze the reasons and ways of changing various software objects, and then analyze the law of their influence. [0003] Change is a key issue in the software development process, and an excellent software change impact analysis algorithm is very important for the entire software system development. At present, there are many related studies on...
