Dirty data

Dirty data, also known as rogue data,[1] are inaccurate, incomplete or inconsistent data, especially in a computer system or database.[2]

Dirty data can contain such mistakes as spelling or punctuation errors, incorrect data associated with a field, incomplete or outdated data, or even data that has been duplicated in the database. They can be cleaned through a process known as data cleansing.[3]

  • Nonsecretive and discrediting data:
    • sanction immunity,
    • normative dissensus,
    • selective dissensus,
    • making good on a threat for credibility,
    • discovered dirty data.
  • Secretive and discrediting data: Hidden and dirty data.
