Texas Data Exchange (TDEx)

The Texas Data Exchange (TDEx) is a system that compiles law enforcement incident records and other non-intelligence criminal justice information into a central state repository for sharing across jurisdictional lines. The information is available for law enforcement and criminal justice purposes. The greatest value of TDEx is being realized in the wealth of information it brings to criminal investigations. Data pertaining to incidents, suspects, booking and incarceration records, and other criminal justice information is contributed by Texas agencies. Access to TDEx is provided by TXDPS to authorized users at no cost to the local agency.

Department of Public Safety (TXDPS) is working toward expanding the quantity of contributing agencies; however this requires development of customized software tools ("adapters") which function to gather and standardize the agencies' crime incident and other data and submit it to the TDEx Application. The adapters developed under the TDEx Contract will allow for authorized regional and national integration of this same data without the burden of additional costs to contribute the data to those other systems. Once the information is gathered from local databases, it is populated in TDEx where it is combined with the data from other sources and optimized for searching by authorized TDEx users. Data in TDEx is shared or combined with other data sources only with the approval of TXDPS.

TXDPS requires that every agency using TDEx and/or contributing data must execute a TDEx User Agreement plus the TDEx Agency Administrator Assignment (appoints one individual to administer all of the agency's TDEx users and acts as TXDPS point of contact). The User Agreement and Agency Administrator form must be signed by the head of your agency (or their appointed designee authorized to enter the agency into contractual obligations). You may fax or email a soft copy; however please return a completed original to the TDEx Program Office as soon as possible:

It is important to note that all users (both Agency Administrator and Basic User) must use an established email account through LEO (Law Enforcement On-Line network) or through your agency’s law enforcement/government (ending with “.us” or “.gov” only) email account since the data accessible is subject to Criminal Justice Information Security (CJIS) Policies, a public email account is not permissible. If you work for a law enforcement, criminal justice, or public safety agency, you can join LEO, too.  Just send an e-mail to leoprogramoffice@leo.gov or call 202-324-8833.

National Data Exchange (N-DEx)

The TXDPS TDEx Program works closely with the Federal Bureau of Investigation, Criminal Justice Information Systems (CJIS) National Data Exchange (N-DEx) Program Office including promotion of Texas incident based records and related criminal justice information contributed to TDEx by local criminal justice partners for improved information sharing at the national level. The FBI CJIS Division N-DEx System provides criminal justice users nationwide, with a powerful new investigative tool to search, link, analyze, and share criminal justice information such as incident/case report and arrest data, booking and incarceration data, probation/parole data, and expanded DOJ data sources on a national basis to a degree never before possible. N-DEx allows authorized users to detect relationships between people, places, things, and crime characteristics and to link information across jurisdictions. N-DEx was developed in collaboration with the law enforcement community and is accessible to authorized users within law enforcement and criminal justice communities.

N-DEx is integrating  information compiled through OneDOJ (formerly R-DEx) which is a repository for DOJ law enforcement components' (Bureau of Alcohol, Tobacco, Firearms, and Explosives; Bureau of Prisons; Drug Enforcement Agency; FBI; and United Marshalls Service) data that enables internal sharing of investigative information within the Department.
