Very interesting.
If non-tech people can learn a simple query language for their analytics
purpose, it would be worth trying.
I think some "abstraction layer" is needed between non-tech users
and DBMS to allow them to issue queries themselves.
I think some query builder could be one of the solutions, and
also some simple query language could be another solution.
I will look into it.
