ABSTRACT

Usually collection of keys are manually driven, hence it’s time consuming. Staffs of organizations have to sign in and sign out for keys in order to accomplish the daily jobs. In the process much time is spent collecting keys for the specific offices. This is because they are expected to write their names, departments, date, time against these respected columns; before they will now sign across the key columns, in a Key Movement Book (KMB) that keeps records keys collection. The present system is a manual driven process, where signing in and out of key is done manually. Hence, the signing of keys is slow and in efficient in terms of checking for keys availability and retrieval. In addition, the naming convention of the keys are don randomly and not in a structured manner.  The collection of keys is insecure.  This means the security risk of a staff coming from one department to sign key for another department is high. This risk coupled with the associated job hazards of the security staff necessitated the analysis of this new with a view to minimizing or out rightly stopping them. The requirements and structure of the new system is analyzed and designed.   The requirement entails component parts of the systems. While the structure describes the system design, in respect to Entity Relational Diagram(ERD), Data Flow Diagram (DFD), Class Diagram(CD).  These diagrammatic tools are used to show the, inputs, objects, processes and outputs of systems in a diagrammatic manner.

Key Words: Entity Relational Diagram (ERD), Data Flow Diagram (DFD), Key Movement Book (KMB), Class Diagram (CD), Key Movement Report (KMR), Key Report Book (KRB)
