So I'm working on a small project that will develop into a startup if the prototype works. It's heavily based on information handling and to supplement the functionality we plan on having an internal user profile database. You are obviously familiar with the functionality of modern database tech. Was thinking SQL, might there be faster/lower latency lookups? Haven't nailed down all the fields yet but baseline will include taxonomy(language topics), historical preferences (general and specific) I can go into more detail by email if you're curious)
