You can use the mapping to map conceptual models and database models onto each other during modeling. You can model each aspect in the right model and keep a clear division between the conceptual and technical data. Simply execute the mapping so that changes made to one model will also have an affect in another model.
You have the option of creating a database model from the conceptual model.
You can then work in both models. You can use mapping to adopt changes made in the conceptual model in the database model. You can view them in a preview before adopting the changes.
Vice versa, you have the option of creating a conceptual model from an existing database model. This makes it easier to start model-driven database development, i.e. mapping is only carried out from the conceptual to the database model.
The mapping marks model elements in the database model as "Created by Mapping" and they have model references to the conceptual model so that you can always track which model elements have come from where.
If you want to change the behavior of a mapping, because e.g.
then you should create your own mapping using the model-to-model software development kit (M2M-SDK).
