HOLMES meaning in Governmental ?

HOLMES 2 (Home Office Large Major Enquiry System) is an information technology system that is predominantly used by UK police forces for the investigation of major incidents such as serial murders and high value frauds.

The system is a single application which was developed by Unisys and McDonnell Douglas Information Systems (in competition, not co-operation) for the Police Information Technology Organisation under a private finance initiative. It provides total compatibility and consistency between all the police forces of England, Scotland, Wales, and Northern Ireland, as well as the Royal Military Police. The name of the system is a reference to the fictional Arthur Conan Doyle private detective character Sherlock Holmes.
