Analysts are modeling online citation payment as a use case. Which set best represents primary actors interacting with that use case?
Select an answer to reveal the explanation.
Short Explanation
Actors are the cast who touch the scene—resident, clerk, payment gateway—not the furniture (tables) or the paint (UI skin). Use cases care who starts and who responds in the flow.
Full Explanation
Use cases describe interactions among actors and the system under discussion. Human roles such as resident and clerk, plus external systems such as a payment gateway, are typical actors in an online citation payment flow. Data schemas, sponsor meeting invites, and visual design assets are not actors. Modeling the right actors keeps the flow analysis focused on who initiates and responds.
