Home Office Large Major Enquiry System
A computerized database used in the investigation of major crimes and other police operations where large amounts of data have to be processed. Now in its second generation as HOLMES2 it makes the investigation process of a major inquiry easier than previous manual systems of filing and retrieving data which proved incapable of handling very large inquiries. It helps investigating officers to identify and plot lines of inquiry and keep track of evidence. HOLMES2 also has a Casualty Bureau function to help coordinate the aftermath of major incidents such as terrorist attacks, floods, or train crashes.
