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 the target model's structure.

Font Color	Meaning
Blue	Modified Model Elements
Green	Newly-Created Model Elements
Red	Model elements that can be deleted. Model elements are not automatically deleted.
Orange	Linked Model Elements
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.
