The scenario
A university deploys an AI chatbot to handle library inquiries. Students interact with the chatbot to search the catalog, renew borrowed books, reserve items, check overdue fines, and ask general questions. Librarians manage FAQ content and review chat logs. The chatbot interfaces with the existing library management system.
What is in this drawing
Read the decisions behind it.
01
Modeled the library management system as an external actor to show integration.
02
Used an extend relationship to allow students to reserve a book directly from search results.
03
Omitted authentication details to focus on chatbot interactions.
This use case diagram can be reused for any chatbot system that acts as a frontend to a legacy system, where the chatbot mediates between users and backend services.
