Chapter 3 Basic Repository Tasks
Impact Analysis
When you create an external shortcut, or when you attach a business rule to an object, a dependency link is created between models or objects.
Dependencies are used to verify the use of an object or model, they can be of two types:
- Internal, when the links are within a model. These dependencies are saved in the model and appear in the Dependencies tab of an object property sheet
- External, when the links exist between models. These dependencies are created during intermodel generation or external shortcut creation, they appear in the Dependencies tab if the related model is opened in the workspace. If the related model is not available, you can use the repository to retrieve external dependencies
Understanding impact analysis
The repository computes and saves external dependencies information in the consolidated models. You can extract this information and display external dependencies in the Dependencies tab of an object property sheet, even when the related models are not available.
This information can be used when you need to analyze the impacts of changes performed on a model or an object in the following way:
- Generation link, you can check if a model has been generated, and the name of the model(s) generated from the current model (column Generated As in Dependencies tab)
- External shortcut link, you can verify if objects in the selected model have shortcuts in external models
