A tactical database is a system of computer files containing information relevant to combat maneuvers, armaments, and the relative strength of offensive and defensive technologies. Most starships carried a tactical database, with which to access information pertaining to shields and weapons. In 2373, Harry Kim, Voyager's operations officer, downloaded a Borg tactical database from a distribution node on board a wrecked Borg cube. Analyzing the information, the crew learned about the conflict between the Collective and Species 8472. (VOY: "Scorpion")
