Data flow diagram for online shopping system

About this data flow diagram for online shopping

The data flow diagram (DFD) shows how data moves between parts of an online shopping system. It focuses on managing e-commerce transactions. The system process starts when the customer performs searches through the system interface. The system takes search criteria from the customer. This includes product names or categories. Then, it generates a list of available products. After selecting the desired products the customer moves their choices to the cart before proceeding to checkout.

When the customer checks out, they provide payment info. The payment gateway then verifies this for transaction approval. Once payment is confirmed, the system makes an invoice and sends it to the customer. The inventory management component updates stock records when items are sold. It also marks ordered products for shipment. The accounting component keeps track of transactions. It creates accurate financial statements and generates analysis reports.

Order fulfillment kicks off by issuing orders. After that, it moves over to delivery management and sends tracking updates to customers. The system marks products as "dispatched and delivered" once they are shipped. The inventory management system ensures product availability is accurate. It also stops overselling by syncing data regularly.

The data flow diagram shows how data flows from customers to the online shopping system. It then goes through payment gateways and inventory control systems. Finally, it reaches accounting functions to ensure a smooth online shopping process. The system works well because each part has a clear job in processing and transferring data. The DFD shows a clear breakdown of how information moves on the online shopping platform.
