Actors, Business Processes and Requirements

 Identification of Actors

An actor specifies a role played by the user or any other system that interacts with the subject. it may represent roles played by human users, external hardware, or other subjects. In this scenario, we got 3 actors they are,

       1. Airline ticket agency.

      2. Passenger.

       3. System.

Business Processes

First when someone needs to travel that person looks for a ride. it may be any transportation method. if someone chooses flight they are our stakeholders. when they chose our agency they are our customers, when a customer (passenger) books a fight A separate booking reference number is given to each passenger. An airplane has several seats that seats have a unique number each number given to each passenger. An airline agency takes a booking fee from a passenger in return they give them a ride that's the whole business process of an airline ticket agency.
