DQL: What Is It Good For?
tl;dr - anything you're doing on Domino, but the message doesn't seem to have reached everyone.
DQL has been at the forefront of my radar since Domino V10 over a year ago. If I remember correctly, documentation wasn't immediately available in Domino Designer's Help, but was soon published online. It's been at the heart of sessions and advances ever since. It's often been discussed alongside the app dev pack, which allows Node.js applications to interact with Domino via the proton task. And judging from a couple of discussions in different fora over the last week, it appears the connection between DQL and the app dev pack seems a little too close. It seems to have led some to ignore DQL assuming it's only for Node.js development.
