ABSTRACT

The principal objective of this project is to help Security Information Systems (SIS) especially NIGERIAN POLICE which is my case study in the area they encounter problems in securing security data-processing and efficient information system. This will be the solution given to handle this problem by transforming the existing manual information system into an automated form and overcome the existing problems of insecurity and delay in data processing. I decided to use an automated database system to enhance information storage and keep track of security information. Again, doing this will ensure that there is an effective security information system computerization. To achieve this, Visual Basic 6.0 is used for its implementation.
