The Memex system includes a hybrid relational and open text-search database paired with an intelligence engine that compresses data. That allows users to quickly and simultaneously search multiple databases without knowing where the data might be housed, said Mike Himley, general manager of the Western region at Vienna, Va.-based Memex.

For example, a user could search for references to a red Ford car without having to search in a vehicle field, and the system will bring back all references, including those that might be in Microsoft Word files from another officer's case notes, Himley said.

Memex, which specializes in analysis tools for law enforcement and intelligence agencies, is now installing a similar system in the Ohio attorney general's Bureau of Criminal Investigation & Identification. In addition, the state of New Jersey announced last year that it would use tools from Memex for statewide data analysis.

London's Metropolitan Police Service, also known as Scotland Yard, has been using tools from the company since 1993.
