Sorry, I realize my first message wasn't as clear as I wanted.

You would not expose the internal implementation, you would simply accept SQL queries, maybe against a separate view of your SQL database, or maybe against a custom backend.

SQL shuould be the query languange, not the implementation.

That’s exactly what I meant as well. SQL may be the implementation, but if so with a well designed exposed schema, not with the application internals.
