The Starfleet database was a record of historical data maintained by Starfleet since the mid-22nd century. The database continued to be used during the 23rd century and 24th century by the Federation Starfleet.
In 2256, at the request of Saru, the Starfleet database listed the most decorated captains in Starfleet history: Robert April, Jonathan Archer, Matthew Decker, Philippa Georgiou and Christopher Pike. (DIS: "Choose Your Pain")
