I'm an amateur programmer who has never worked with databases. I *think* that using databases (namely SQLite) can help with some of my Autoit projects, but I'm having trouble determining exactly how. I'm hoping the database literati here can help explain a particular aspect about databases that is giving me trouble. My simplified situation is this. A user enters his height and weight into a program and, based on that height/weight combination, the program returns a group, either "A" or "B."
