Doctor Dobb's Journal had a cool article once about using Prolog to prescribe medications, in particular avoiding conflicts with other prescriptions. It would have been in the early 2000s. According to the author, they used Prolog to rewrite the app from a tangled mess of nested if statements. After the rewrite, the rules could be managed by pharmacists instead of programmers. It seemed like a good application to me. I studied Prolog in college but have never used it professionally. I keep hearing good things about Datalog, which I know even less about. . . .

That's a cool case study!

It hits right at the core of the appeal (these kind of solvers need to be designed, if you grow them organically you get the if statement from hell) and also the challenges (not many managers would run with the idea of "the users will be doing something that looks a lot like writing code").
