Data flow diagram for online car rental system

About this data flow diagram for the online car rental

The data flow diagram (DFD) demonstrates the information exchange between system components that handle an online car rental system. The customer begins the system interaction by using the available cars search feature. Customers give search details like car type, rental duration, and location. The system processes this info and returns a list of available cars. The customer moves to book the selected car to start the rental process.

The system generates an invoice with details about the chosen car and rental info. The customer needs to confirm this information. The customer examines the invoice before performing payment. The payment gateway handles all payment transactions by ensuring secure processing of payments. The system marks the rental order status as rented after confirming the payment from the payment gateway.

The accounting part manages money by making records and reports for rental processes. After selecting a car the system allocates it to the customer therefore completing the rental order. The user gets a confirmation message. This message contains all the rental order details, such as rental duration, car specifications, and payment verification.

The data flow diagram shows the full journey of data. It starts with the customer using the online car rental system. Then, it goes through the payment gateway. Finally, it reaches the accounting component to complete the needed operations. The system works well together. Each part has its own job in data processing and transfer. The DFD delivers a systematic representation of the data movement patterns in the online car rental platform.
