Dirty data is inaccurate, incomplete or erroneous data, especially in a computer system or database.
In reference to databases, this is data that contain errors. Unclean data can contain such mistakes as spelling or punctuation errors, incorrect data associated with a field, incomplete or outdated data, or even data that has been duplicated in the database.
Famous quotes containing the words dirty and/or data:
“All parents occasionally have ambivalent feelings toward their children. We love our kids, but there are times when we don’t really like them, or at least we can’t stand what our children are doing. But most of us keep those feelings to ourselves, as if it’s dirty little secret. It doesn’t fit in with our images of what we should do and feel as parents.”
—Lawrence Kutner (20th century)
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
