If you go from the data tab of a db service, to a different service, the view is a blank screen. It should probably just default to the first options of that screen. Very similar to how a volume works. If you click on a volume from a tab that it doesn't have, it takes you to the metrics tab (the first options). But otherwise (if you were on settings on a different service) it takes you to settings. I imagine this should be extended to all services as a generic fallback.
