In a HRIS data modeling exercise, which element in a data flow diagram stores data about a process like job requisitions?

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

Answer: (A)

Think of a data flow diagram as showing how information is stored, moved, and processed. Among its elements, the data store is the repository that holds data for later use by the processes. Storing data about a job requisition—such as requisition ID, title, department, status, and approvals—fits this role because it represents the saved record the system can read from or update as requisitions are created or changed. The process would be the activity that uses or updates that stored data, a data flow shows how data moves between elements, and an external entity is something outside the system that interacts with it. So, the element that represents the place where the requisition data remains is the data store.
