Prolog has very little syntax, usually it's not particularly hard to serialise your data structure directly into Prolog code and consult it. If your data is streaming you might have to resort to assert/asserta/assertz/retract, depending on your use case. log("2024-10-22", "09:09:23", "Mozilla", "/login"). log("2024-10-23", "09:09:24", "Safari", "/dash"). log("2024-10-24", "09:09:25", "Chrome", "/user"). log("2024-10-25", "09:09:26", "Brave", "/login"). Implementing a transform of a web server log file into Prolog can be as simple as this. In practice you'll have more like ten or twenty fields, of course. Then you can query along the lines of log(Date, Time, "user agent constraint", Resource). and don't have to be as diligent as when stacking grep:s or such. If you already keep all your logs in analytics databases the example isn't very good, but it ought to be easy to see how this trivial technique can be applied elsewhere.
