No, I don't want to use SQL on the front-end, nor on the back-end (except as a final translation). I want all my business logic, both front- and back-end, represented in data structures that use language as close to the domain-level as I can get while still allowing flexible querying and manipulation. I want queries that seamlessly mix blob files, SQL records, and code-as-data ("plugin" code properly source-controlled and tested, but that contains database-like IDs and hooks that allows it to be joined in-memory to SQL records). I want an abstraction layer that makes sense for the domain I'm working in, and I mean something specific when I say "abstraction layer". I want a basic level of self-awareness to the application where it knows its own topology and that can be used to generate API documentation, help files, API endpoints, etc. I want security to be an emergent property of this setup -- where exploits are preemptively disallowed simply because they are not sensible domain operations -- rather than trying to come up with an exhaustive list of all the clever ways someone could write exploitative SQL. So, no thanks.
