National Databases
• “National” is a misnomer: – While current multi-jurisdictional databases contain millions of records (often 900-million or more), there exists no single, national database that contains all criminal records in the US • These databases include only those records from various government and law enforcement entities, counties, sex and violent offender registries and other sources that have been made available for purchase • Data cannot be 100 percent accurate, complete or up- to-date • “Clear” product is not Compliant with Licensing or Hiring

Databases - continued
• Data structures are not always reliable: – When combining several different databases into one, the methods used to structure the data will impact search results – For example, when a query is done using “ROBERT SMITH,” results returned may or may not include ROBERT A, BOB, BOBBY, and ROBERTO … whether separate queries must be made for each name varies from one database to another • Extraction Technology often applied • Ensure identifiers • Avoid duplicated records • Use as pointer only, “Hits” must be verified
