How to change model information in strict structured analysis support system

摘要

The present invention relates to a processing method when changing model information in a strict structured analysis support automation system. First, verification of grammar and semantic rules supported by a strict structured analysis automation system in which the present invention is realized for change information before changing the model information. Only correct and accurate model information can be changed through change, and when the model information is changed, not only the corresponding model but also the related model information is changed together. To be deleted. When changing or deleting such model information, all definition information of the object including the characteristic model of the object is changed and deleted.In particular, when the data item is changed, the data element and the undefined data which are the lowest constituent units of the data item are changed. By making changes and deletions, a pure and consistent analysis model is maintained to enable rigorous analysis, such as verification of the rules for creating model information and consistency rules between models.
