Explanation / Answer
1. Salesperson access to Payroll file - A salerperson should not have access to payroll file. Payroll files are related to employee's paychecks. The payroll file enables accounting staff to pay the employee. HR staff and accounting staff have access to these files.
2. Inventory Programmer access to Payroll transaction log - An Inventory programmer should not have acess to any payroll data. Payroll transaction log records all the transactions and changes made to the database by each transaction. Thus this is a very important file and its access is restricted. This data is used for backup.
3. Human Resource Manager access to Payroll Program Code - Human Resource Manager should have access control to Payroll file and transaction log but cannot have acess to payroll program code. Only Payroll programmer is resposible and can have access control to Payroll Program code.
