Airline Reservation System Activity Diagram | UML

Airline Reservation System Activity Diagram – is one of the UML Diagrams that is used to illustrate the behavior of the system towards its users. So in order to understand about how would the system process the airline ticket reservation through online, this activity diagram was designed. It shows the series of interactions and activities happens in processing an airline ticket reservation online, as well as the transaction management made in the back end of the system.

The users of this Online Airline Ticket Reservation System would be the passengers and the airline staff and they are essential in creating its activity diagram. By determining the users of the system, it would be much easier for you to build the interactions and activities in the system. Then you will be able to foresee the behavior of the system towards its user. and this will make you aware that your system must be user-friendly and effective for its users.

What is an Online Airline Ticket Reservation System Activity Diagram?

To have a clear understanding about it, let me tell you the system activity diagram purpose and role. The Airline Reservation System must have an activity diagram so that the programmers will have the basis on how should the software approach its users. It is because, the activity diagram guides the programmer in creating the software and its must-have behavior. So to achieve a friendly and effective or easy-to-use software, then you must also complete the activity diagram.

Through the activity diagram, you’ll be able to illustrate the flow of activities and know what should be the interactions between the system and its users. Your readers and users will also be guided on how would they use the system by looking into its activity diagram. So its best for you to explain your thoughts on Airline Reservation System through activity diagram.

You must be familiar with these symbols in order for you to distinguish what should you put in the illustration to avoid misunderstandings. This is also to educate you about the activity diagram symbols used, so you and the users would understand the system’s behavior.

In addition to that, being familiar with these activity diagram symbols will help you show the detailed parts and interactions that should happen when you develop the System. Then this thought enables you to have right ideas on how you would develop the system that you want.

Additional Knowledge

The activity diagram works perfectly with the other UML Diagrams which were available also on our site. They are the Airline Reservation System Use Case Diagram, Data Flow Diagram, Entity Relationship Diagram and many more. These diagrams served as the blueprint designs to foresee the needed functions of a working Airline Reservation System.
