Sequence Diagram Flight Reservation System Assignment

order Diagram Flight Reservation System - Assignment ExampleThe sequence diagram is a searing part utilized in procedures of analysis and design documentation of user requirements. The sequence diagram is a tool of Unified Modelling Language (UML) that jibes the interaction of different actors with the system in order to stay a result/response (Bell, 2004). The epoch diagram is bingle of the most usable and useful diagrams to represent the interaction of one or more objects interactions with one or more systems. It is pertinent to mention present that we have to develop / draw a Sequence diagram for each and every rehearse Case. The Sequence diagrams are used to model the usage scenario of the system, the logic of the methods and logic of the service. The sequence diagrams are used to bring out the complicated operations, methods or functions in graphical or pictorial mode. Moreover, it also represents the services provided by the system to their clients, for example, the w eb services i-e online flight reservation system. The Use Case diagram enables modelling of a trade view of the scenario, the Sequence diagram contains implementation details of the scenario, including the objects and classes that are used to implement the scenario, and messages passed between the objects (Ambler, 2012). As per the sequence diagram (given below) of the online Flight Reservation System and the definition of the sequence diagram, the actors that were identified in Use Case Diagram ( guest, website) has been utilized in the Sequence Diagram. The first actor is the Customer that would interact with the Website (system). As shown in the following figure, the customer does all the interaction with the system from attempting flight till the provision of the entrap code. Initially, the customer sensory(a)s the website of the service provider (airline or agent of the flight reservation) and clicks the search flight tab of the website. The website would open the flight se arch form and the customer has to enter the required information includes the departure and arrival airport, one way or round trip, the date of departure and return (if round trip) and the recite seats / tickets. The customer submits the form and after processing, the website shows the search results. At this point the customer can go back to the search page and re-enter all the information, otherwise, the customer can select and book the flight. The website provides the review page on with payment information. The customer has to fill the form with required information include full name, passport number and payment method (credit card information). The website provides the confirmation page and the customer confirms the booking. The system processes the customers pass along and presents a personal identification code (PIN) for the future reference (Popkin Software, 1998). Sequence Diagram Reference key out Janssen, C., 2010.
