| Abstract: | This paper designs a security subsystem based on password protection and triggers mechanism in database management systems. Structure and function of the security subsystem is described in a payroll management system as an example of how the security subsystem gives additional security from possible intended or accidental attacks to the entire database system. The security subsystem involves password protection, triggers and improved physical storage mechanism, which combine together to be integrity to enhance security performance.Implementation of the security subsystem in a payroll database has proved its effectiveness. |
