The database directly used for Mendix applications will follow the app Domain model structure. Thus using an existing DB with an existing scheme cannot be used. Mendix will override the existing structure.
You do have 2 main options
- When database is also used for other apps/systems;
- Setup the domain model as data is used in the app
- Integrate with the database using
- When database is only used for the Mx app; You transfer the data from the existing data base
- Setup the domain model as data is used in the app
- transfer the data to the new database using
Hope this helps
