NATIONAL INFORMATION EXCHANGE MODEL

The Law Enforcement National Data Exchange (N-DEx)

The National Data Exchange (N-DEx) is a repository of criminal justice records, available in a secure online environment, managed by the FBI’s Criminal Justice Information Services (CJIS) Division. N-DEx brings together data from criminal justice agencies throughout the United States, including:

  • Incident and case reports
  • Arrest reports
  • Computer-aided dispatch calls
  • Traffic citations
  • Narratives
  • Photos
  • Supplements
  • Booking and incarceration data
  • Parole/probation information

N-DEx automatically correlates and resolves data from open and closed reports to detect relationships between people, vehicles/property, locations, and/or crime characteristics. N-DEx “connects the dots” between data that are seemingly unrelated. N-DEx supports multijurisdictional task forces—enhancing national information sharing, linking regional and state records management systems, and enabling virtual regional information sharing. N-DEx provides no-fee access to national data in real time, with results returned in a matter of seconds, based upon the user’s Internet connection. How does N-DEx work? Electronic records are mapped in Extensible Markup Language, based on NIEM and Logical Entity Exchange Specification standards for electronically sharing criminal justice information. The records are then electronically transmitted to N-DEx.
