FQL: Functional Query Language - General

Welcome to the Functional Programming Zulip Chat Archive. You can join the chat here.

Chapter 3 of 7 Sketches of Compositionalily mentions FQL (Functional Query Language) as an alternative to traditional SQL schemas, queries, and migrations using categories, functors, natural transformations. Unfortunately, I couldn't find PDFs for most of the papers cited. Has anyone seen FQL implementations? How about FQL in the wild?

Torsten Schmits

isn't there a link to the FQL page in the book?

Pedro Minicz

I read it a while ago and don't remember seeing any. Also skimmed through earlier and didn't find anything.

Pedro Minicz

Skimmed through the chapter again and no links on sight.

I couldn't find free copies of the older papers cited online, unfortunately.

So apparently it _was_ FQL and it's now CQL

And David's book has been seen in the wild at Galois. https://smile.amazon.com/Category-Theory-Sciences-MIT-Press/dp/0262028131
