User Interface - Drop Down Lists

[gb]

I'm relatively new to EA and I am working on a model that starts with a business process and links to  a User Interface Model.  

My question is while I am using the User Interface Model, I can add items such as Drop Down lists or Text Fields.  What I don't see is how I can link these objects back to the ERD diagram that I have.  The opposite is true as well, if I take a database field from the ERD diagram and drop it onto a User Interface model, I don't see how I can identify that field on the Screen Object as a Text Box, Drop List, etc.  

Thanks

There's really no standard method of linking your data model to your user interface model.

Suggestions I've seen so far are:
- association with the option "Link to Element Feature"
- tagged value of type REFGUID
