Not being a DBA nor do I play one on TV and I certainly have never had enough sleep at a Holiday Inn Express to even think I could do that...
I agree in that the Data Architect should have a background as a DBA in order to intelligently design and model the intended structure understanding the backend implications.
Currently the enterprise architecture team here builds the models...and the DBA's get to make things work around that as far as I can tell. we don't get much interaction on that side of the fence.
We just get the "we need you to monitor this...here's a query to run and do X, Y, sometimes Z, and on the third thursday of a month with a blue moon do AB and C with the results" on the backend.
Clik here to view.
