Angosian senatorial database
From Memory Alpha, the free Star Trek reference.
The Angosian senatorial database was the central computer database of the Angosian senate from Angosia III.
Due to the petition for membership in the Federation in 2366, the USS Enterprise-D copied the complete database into the ships computer.
When Counselor Deanna Troi and Lieutenant Commander Data searched the database for information about Roga Danar, they learned that he was an Angosian soldier, but they found no reason why he was imprisoned in the penal settlement at Lunar V. The database included several records about Danar such as his two promotions to the rank of a subhadar. (TNG: "The Hunted")
