Starfleet database

From Memory Alpha, the free Star Trek reference

The Starfleet database was a record of historical data owned by the Starfleet in the mid-22nd century. The database continued to be used during the 24th century with the Federation's Starfleet.

In 2151, Subcommander T'Pol ran a check through the Starfleet database and found that Charles Tucker III was the first recorded human male to become pregnant. (ENT: "Unexpected")

In 2373, Captain Kathryn Janeway searched the classified Starfleet database for information on the Borg to aid in the USS Voyager's trip through their space. (VOY: "Scorpion")
