I think of it as being something implicit, rather than explicit. When you execute a client program, the runtime can inspect the client and issue the "Pull()" to the dbms at connect time.

Yes yes!

And these bindings would be declarative, and probably expressed as relations. And they could be dynamic, such that if you have a table widget bound to a table/view/query, as the table was updated, that would be reflected in the contents of the widget, dynamically.

I didn't quite understand this part. I usually think of clients as having the schema they are written against "built-in." This makes it sound like clients are using dynamic schema. That makes sense for ad hoc queries but not so much for client code, which I think of as fixed.
