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 is 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.

Electronic records are mapped in Extensible Markup Language, based on the National Information Exchange Model and Logical Entity Exchange Specification standards for electronically sharing criminal justice information. The records are then electronically transmitted to N-DEx.

The N-DEx User Interface
The easy-to-use interface allows users to search all N-DEx data fields from the main search tab on the homepage. To conduct a search with more specific controls, users may click the Advanced Search tab located to the right of the main search tab.
N-DEx features a set of filters along with a Reason and History tab, which are located along the left side of the home page.
The filters may be used on any search and may be applied to the results as well. Filters can be used individually or in combination with one another.
Filters include geographic location, date, data sources, result filters, and external filters. This functionality provides fine granularity for searching and narrowing search results.
State-of-the-art tools for viewing, analyzing, and understanding the data returns can be accessed via the tabs at the top of the page. Also, targeted search links reside above the N-DEx logo and provide the user with the option to specifically define a search for people, places, and things.
