Linguistic database

The linguistic database was a compiled collection of known languages. They were used by the Vulcans as early as 2151, when they shared samples of Klingonese with United Earth Starfleet. The Enterprise later maintained its own database. 

In 2161, shortly before returning to Earth to decommission Enterprise, Ensign Hoshi Sato figured she would need a week to purge the linguistic database. 

The linguistic database played a role in Starfleet finally managing to communicate with the Tamarians. 

Borg drones also maintained a linguistic database, without which they were unable to assimilate information.
