The four primary functions of CODIS are:

  • DNA profile entry and management: manual entry of DNA profiles in the database
  • Searching: the function that allows database profiles to be searched
  • Match management: the function that manages search results; for example, it allows a laboratory to record and distinguish whether a particular match is an offender hit or a forensic hit, and whether the match is within the state or not
  • Statistical calculations: the function that allows laboratory personnel to calculate profile statistics to show how rare or common a DNA profile is
