When a data flow diagram is used to document the HRIS function of administering job requisitions, which symbol should represent the job requisitions?

• A. Data store
• B. Process
• C. Data flow
• D. External entity

Answer: (A)

In a data flow diagram, data that is kept in the system as a record is shown as a data store. A job requisition is a stored record within the HRIS, so it belongs as a data store symbol (the symbol that represents persistent data kept by the system). The other symbols serve different roles: a process represents an activity that transforms data, a data flow shows the movement of data between elements, and an external entity represents someone or something outside the system that interacts with it. So the requisition itself is the stored data the HRIS maintains.
