Mapping the Online Flight Booking Logic
Visual Paradigm’s AI Activity Diagram generator transforms natural language prompts into precise, professional diagrams—perfect for modeling complex business processes like online flight booking. In this example, a user requested a visual representation of the end-to-end flight booking journey through a travel portal. The AI Chatbot interpreted the intent and delivered a fully structured activity diagram, capturing every key step from flight selection to e-ticket delivery.
What sets this solution apart is its ability to evolve through conversation. When the user asked, *”Can you explain how the system handles seat selection conflicts or unavailability?”*, the AI didn’t just answer—it enhanced the diagram with real-world logic, adding a conditional branch to handle seat availability checks and fallback options.
Key Elements of the Diagram
The generated activity diagram illustrates a clear, decision-driven workflow. It begins with the user selecting a flight, followed by entering passenger details and choosing seat preferences. A critical decision point evaluates whether payment is required—common for non-refundable or premium bookings.
For payment, the system includes a retry loop with a maximum of three attempts, ensuring resilience against temporary failures. If payment succeeds, the booking is confirmed and an e-ticket is sent. If it fails after three attempts, the process cancels and notifies the user.
When the user raised a follow-up question about seat availability, the AI responded with a refined version of the diagram, now including a check for seat availability. If the selected seat is taken, the system notifies the user and offers alternatives—such as available seats or a different class—before proceeding to the summary and payment steps.
Extending the Model with Real-World Intelligence
Visual Paradigm’s AI Chatbot doesn’t stop at diagram generation. It understands context and can refine, expand, or restructure diagrams through conversational interaction. In this case, the original flow was enhanced to include conflict resolution logic, demonstrating how the platform supports iterative design thinking.
Users can also request related diagrams—such as a C4 Component Diagram to visualize system architecture or a Sequence Diagram to detail interactions between the user, booking service, and payment gateway. These extensions are seamlessly generated using the same conversational interface.
Why Visual Paradigm Stands Out
Visual Paradigm is the comprehensive AI-powered visual modeling platform that empowers teams to design, refine, and document systems with minimal effort. With support for UML, ArchiMate, SysML, C4, and mind maps, it caters to developers, architects, and business analysts alike.
Its AI Touch-ups feature allows users to modify diagrams via chat—adding shapes, translating text, or rephrasing logic—making it ideal for agile environments where requirements evolve rapidly.
For those ready to experience the future of visual modeling, the logical next step is to explore the AI Chatbot in action.
