Areas where computer technology has helped sheriff's offices include arrests, booking, commissary control, criminal histories, fingerprinting and identification, inventory, jail management, mug shot imaging, payroll, records management, reporting stolen property, and warrant tracking. Many companies offer a wide variety of database management systems that can be adapted to specific needs. Aspects of law enforcement and jail management that can be automated include administration (shift scheduling, budget tracking, fixed asset inventory control, and vehicle maintenance), civil processes, criminal warrants, drug investigations, and criminal investigations. In the case of criminal investigations, computer software is available to track investigative activity by case number and to update incident files directly by investigators. Computer software is also available for administrative and investigative recordkeeping. Computerized recordkeeping systems allow crime data to be maintained for statistical purposes and property and evidence records to be tracked.
