Mapping Preview
Model elements are created and modified during mapping. It depends on the selection of existing model elements as to what is created or modified.
Prerequisites
You have started the Mapping editor with a mapping between the database schema and the conceptual model.
An engineering action with the Simulate tag is defined.
You have selected elements and the target model is set.
Context
You want to know which model elements are created or modified by the mapping before you make these changes.
The model elements are highlighted in color in the structure of the target model.
| Font Color | Meaning |
|---|---|
| Cyan |
Linked model elements The existing target element has been linked with the source element using a mapping dependency and has not otherwise been changed. |
| Blue |
Modified model elements The existing target element has been modified and linked with the source element using a mapping dependency. |
| Green |
Newly-created model elements A new model element has been created in the target, the properties have been set according to the rules and it has been linked to the source element using a mapping dependency. |
| Red |
Model elements which can be deleted Model elements that can be deleted. The model elements are not deleted automatically. You can verify and delete them here. |
| Black | Unmodified model elements |
How to proceed
-
Select Mapping>Map Model>Preview.
You can see the changes made to the model on the right-hand side of the mapping area if you carry out the mapping. The model elements are highlighted in the model structure.
Note
The changes shown in the preview are not identical to the changes that will be carried out by the mapping. As the mapping result depends on what already exists and nothing is created or modified for the preview itself, then many changes may not be simulated. If e.g. a package was created as new, then all contents of the new package cannot be simulated.
-
Select Mapping>Filter>Show All.
The unmodified model elements are shown in Black.
