The development in technology has brought about using computer system to solve practical problems in various fields of work. This advancement leads to automation of system processes. This paper studied the manual processing of Prisoners Information in Yola Prison of Adamawa state, with a view to developing an “Automated Prison Information System”. This system is expected tol provide an easier way of computing prisoner’s information, reliable storage of data, easy access and retrieval of information to authorized users, and also to provide high security for prisoners’ record. The software has features for adequate registration of prisoners both on the day of jail and discharge. In addition, there is provision to search and view reports of both current and discharged prisoners. In comparison to the current system, the prison inmate information system is more secure, flexible, provides more user feedback, reduces the workload, prevents erroneous data and provides more functionality.
