If my data is document based then how is SQL going to be more concise and expressive than JSON ?
Say I have a domain model that involves a primary object e.g. User with lots of maps and arrays then how is SQL going to be better then ? Lots of tables and joins better than a single document. I think not.
If your data is a User object with maps and arrays, and you design a data structure which gets you the result in exactly that format, you _are_ giving up the ability to ask other questions of this data. You are giving up the ability to ask _many_ different kinds of questions (expressive) in a relatively simple way (concise).
