Data flow diagram for vending machine

About this data flow diagram for the vending machine

The data flow diagram (DFD) for the vending machine system shows how information flows between parts that manage the vending machine. The vending machine system begins when customers select items on the interface. The vending machine system first saves customer actions. Then, it checks its database for product details, such as stock availability and transaction records.

The system verifies inventory availability for selected items by the customer. The customer moves to payment processing after verifying stock availability. The payment gateway handles payment transactions by executing secure payment completion. The payment processing completes then the system updates stock records and creates an entry in the database.

The cloud server is key for syncing inventory data and processing payments. This service helps the vending machine system keep track of inventory levels and transaction records. The owner uses the system to monitor inventory. They request suppliers to restock. They then add new products to the vending machine.

All key data, like product details, stock levels, and sales logs, is stored in the database. This is the main storage place. The data flow starts when customers use vending machines. It goes through payment gateways, and then to cloud servers. Finally, it reaches owners before entering the database.

This shows the order of vending machine operations. Each system part handles specific tasks for processing and data transfer. This keeps the system working smoothly. The data flow diagram presents a well-organized view of how data moves through the vending machine system.
