1 | Input Problem Domain

Specify the problem domain: Airline Reservation System. This initial step equips the AI with the context needed to define the platform’s purpose, user roles, and core workflows for both travelers and airline staff.

2 | Generated Problem Description

The AI processes the given domain and produces a detailed problem description that covers flight scheduling, dynamic pricing adjustments, integration with global distribution systems, booking confirmation, and secure payment handling. This generated description can be tailored to match the unique requirements of a specific airline network before moving forward.

3 | Identified Candidate Classes

From the outlined description, the AI identifies primary domain classes including Airline, Flight, Booking, Customer, and Payment. Each class is described with its function, justification for inclusion, and—where applicable—reasons certain detected elements may not qualify as classes. All information is neatly organized in collapsible sections for convenient review.

4 | Identified Class Details

After confirming the classes, the AI lists attributes and operations for each entity. Attributes capture essential information such as flight numbers, passenger details, and booking statuses, while operations represent actions like reserving seats, processing payments, or issuing tickets. This breakdown provides a precise specification for each class’s responsibilities.

5 | Identify Class Relationships

The AI maps the relationships between the identified classes, showing which entities are connected, the role of each within the relationship, a brief explanation of the connection, and the type of association—be it aggregation, composition, or standard association. This step offers a clear picture of how components interact in the booking ecosystem.
