The purpose of this National Institute of Justice (NIJ) InfoTech Data Standards compact disk is to provide the Public Safety community with valuable documents towards data sharing efforts. The InfoTech program was initiated to answer the need for an integrated and secure information network solution to facilitate sharing of public safety and criminal justice information. In order to accomplish this goal, the InfoTech team set out to establish a global search capability, allowing criminal justice professionals to query all relevant CJ repositories, and quickly obtain critical information.
Information sharing technologies traditionally fall within two approaches: the data warehousing approach and mediation across distributed heterogeneous data sources. The InfoTech program was initiated to answer the need for an integrated and secure information network solution to facilitate sharing of public safety information. In order to accomplish this goal, the InfoTech team set out to establish a global search capability, allowing criminal justice professionals to query all relevant CJ repositories, and quickly obtain critical information. The InfoTech program chose to use a technical approach providing mediation across distributed heterogeneous data sources.
InfoTech's technical approach uses tailored data integration to meet and satisfy specific state and local jurisdictional needs. In addition, this was layered with distributed, rule-based commercial security integration. Critical to the success of any shared data integration project is the development of shared standard data objects. To this end, NIJ has developed a set of standard data objects to which criminal justice agencies can map their own data objects through which the software can then share the information across data sources, irrespective of their specific data schema.
