It's an open question.

Ruby / Rails has Arel (note that Arel is data access abstraction,
not database access abstraction. But Database access is a part of data  
access).
Haskell has Database.Persistent.
I think other languages will support similar library in the future.

I don't have a detail.
I already implemented it if I had a detailed design.
In my D tasks, database related task is low priority...
