About the use case diagram example

The use case diagram for an online pharmacy system illustrates interactions among primary actors—Customer, Pharmacist, and Administrator—and the system’s functionalities. Customers interact with the system to browse medications, place orders, view order history, and manage prescriptions. Key use cases for customers include searching for medications, adding items to the cart, checking out, and tracking order status. Pharmacists engage with the system by verifying prescriptions, dispensing medications, managing inventory, and providing patient consultations. Key use cases for pharmacists involve verifying prescriptions, updating inventory levels, filling orders, and advising patients on medication usage.

Administrators manage the platform by adding or removing medications, handling user accounts, and resolving technical issues. Key use cases for administrators include managing medications, user accounts, and addressing technical support requests. The diagram uses ellipses to represent these use cases, with lines connecting the actors to their respective actions, emphasizing workflow and coordination for effective online pharmacy management. This visual representation aids in understanding the system’s design, identifies potential areas for improvement, and ensures a streamlined and efficient experience for all stakeholders involved in the pharmacy process.
