Law enforcement deals with various types of information including crime reports, statistics, criminal histories, employee records, and business/individual registrations. Data can be entered using word processing, imaging, optical character recognition, bar codes, fax, or downloading from a network. When considering an information management system, law enforcement must account for data storage devices, backup requirements, system configuration (network vs standalone), security, and administration. Mass storage options include RAID hard drives and optical disks like CD-ROM.
