System Design

Develop an activity diagram, with swimlanes, for an instance of an online purchase where:

The purchase is made using a wholesale distribution platform such as eBay or Etsy.

The product is being sold by an independent seller who will fulfill the order themselves and send tracking information back to the distribution platform.

The purchase is paid for via the customer's PayPal account $($assume a smooth transaction here$).$

The customer can check the order status on the distribution platform

The customer receives the product.
