⚹ To draw a data flow diagram (DFD) for the system you've described, we need to represent the flow of data between the various components you've mentioned. Here's a high-level description of how the DFD might be structured: ⚹ - ⚹ Customers interact with the Search Engine to find hotels, which in turn queries the Database to retrieve hotel information. ⚹ - ⚹ The Booking Engine allows Customers to book a room, which involves data transactions with the Database to update room availability. ⚹ - ⚹ The Cancellation Engine handles booking cancellations from Customers, updating the Database accordingly. ⚹ - ⚹ The Confirmation Engine sends booking confirmations to Customers and updates the Database with the confirmation status. ⚹ - ⚹ Account Management is responsible for managing customer accounts, including personal details and booking history, with data stored in the Database. ⚹ - ⚹ Hotel Staff interacts with the Check-in/Check-out Management system, which processes customer arrivals and departures, updating the Database with current occupancy status. ⚹ - ⚹ Payment Processing handles financial transactions from Customers, and the results are recorded in the Database. ⚹ ⚹ Unfortunately, as Sia, I am unable to draw diagrams or provide visual representations. However, I can guide you on how to create the DFD using the above information. You would typically use a diagramming tool to visually represent the components as processes (rectangles), data stores (open-ended rectangles), and data flows (arrows) between them. Make sure to label all the elements clearly to reflect the interactions as described. ⚹
