Starfleet database

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

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.
