This template is a user interaction diagram for an e - commerce system. For the "customer", actions include "login", "manage products", "handle orders", "generate reports", and "assign deliveries". The "Admin" can "Register/login", "Browse/search product", "add items to the cart", "place orders", "track delivery and place history", and "make payments". The "Delivery Agent" can "login", "view and update delivery status", and "confirm deliveries". The "Payment Gateway" is responsible for "Validate and Process payment" and "confirm success or failure". The diagram visually represents the various operations and interactions that different entities can perform within the e - commerce system, which is useful for understanding the system's functionality, user - experience design, and for developers to plan the system architecture.
