12. The N-DEx provides centralized, “one-stop shopping” for investigators, analysts and criminal justice professionals.
Arrest
Federal Case
Currently criminal justice agencies across the nation maintain their own Records Management Systems (RMS). These systems are mostly independent of one another and have no ability to link with others on a nationwide scale. N-DEx resolves that limitation. N-DEx is not in competition with other existing systems. N-DEx is designed to complement and enhance the capabilities of existing systems. Agencies from across the nation submit copies of their data to N-DEx. Once the records are submitted into the N-DEx system, they are accessible to N-DEx users from across the nation.
Now, investigators can link an arrest in California with a traffic citation in South Carolina, an incarceration report in Texas, and a federal case in New Jersey.

What the system can do…
These are all documented benefits that have been shared with us by users via the recent user assessment.
Improve tracking/notification on suspect status – The Subscription & Notification feature gives users the ability to set alerts that will notify users when new records on suspects are entered into the system.
Facilitate deconfliction – The Subscription & Notification feature will notify users if anyone else conducts searches for the same entities or key words, providing them the name and contact information to reach out to other agencies that have similar investigative interests.
Enhance officer safety - N-DEx provides users with information from criminal justice agencies across the nation to give a comprehensive view of the subjects and their past interactions with criminal justice agencies.
Improve hot spot analysis- With the Geo-Visualization feature users can plot activities on a map to show trends and locations of activities.
Improve case management efficiency
Improve capability to identify crime patterns and trends
With the Batch Query function, users may search multiple people, vehicles, telephone numbers, or key words at one time.
N-DEx may also be used for criminal justice employment background checks (cops hiring cops). However, if an agency uses N-DEx for these background checks they must adhere to the appropriate sections of the N-DEx Policy and Operating Manual.

18. How it works.. BANK ROBBERY GUN
N-DEx was designed for ease of use by investigators and analysts. Practitioners from across the nation were asked for input during all stages of development. Criminal justice agencies from across the nation asked for an intuitive system. Accordingly, everything about N-DEx looks familiar to the user.
The simple search feature allows users to conduct a search for any key words, phrases, names, etc. Users may, for instance, conduct a search using the terms metal and theft. This search will return results from any records in the system that contain these words anywhere within the record.
A user may narrow search results by using the filtering system located on the left-hand side of the screen. These filters allow for the narrowing of results by geographic location, date of incident, data owner, or submitting agency ORI.

19. Targeted Search raphael ramirez
Targeted searches allow a user who has specific information about a person, place or thing to conduct a search using structured data elements. A user who conducts a targeted search on a specific name will receive all records from the system that contain that specific name.

20. Integrated Person entity view
The Integrated Person Entity View provides the user a one-page composite of any subject. The system retrieves all records related to a specific person and presents them in a concise, clean format for user review.
N-DEx extracts the identifiers from all records associated with a particular person in order to provide a snapshot of her/his identifiers, associations, locations, property, and any pictures that may be found within the system.
N-DEx automatically connects the dots between seemingly unrelated information. N-DEx helps investigators by providing relationships between people, places and things.
