Online Airline Reservation System Project UML Diagrams
ONLINE AIRLINE RESERVATION SYSTEM UML DIAGRAMS – are diagrams formed by the Unified Modeling Languages that acts as the blueprint for the project development. UML shows the needed diagrams based in UML to guide you in building your Online Airline Reservation project. These UML Diagrams is composed of Use Cases, Activity Diagrams, Class, Sequences and many more.
Here’s how to get you started. Let us discuss why an online Airline Reservation system should have these UML Diagrams, What are UML Diagrams, How to form them and how they worked. In this article you will also know the bonus diagrams that will help you in understanding how the online Airline Reservation System works. Each of these Diagrams comes with complete explanation to let you understand its contribution to the Online Airline Reservation system.
What are UML Diagrams?
A UML diagram is a diagram based on the UML (Unified Modeling Language) that is used to visually describe a system, including its major actors, roles, actions, artifacts, or classes, in order to better understand, edit, maintain, or document system information.
Software engineers uses UML modeling language to provide ready-to-use, expressive modeling examples to users (programmers). Some UML tools create code in a programming language. The UML Diagrams are categorized into two types: the structural diagrams and the behavioral diagrams.
Is it necessary for Online Airline Reservation System to have UML Diagrams? The answer is YES. Its because the UML diagrams are the visual designs or the blueprint of the system structure and behavior. Structural diagrams helps in building the structure of Online Airline Reservation System while the behavioral diagrams in UML helps in determining its behavior towards the user, data inputs and producing an output. All of the UML diagrams works in sync and relatively to achieve a well-engineered project.
How to build an Online Airline Reservation System UML Diagrams?
The first thing that you must do before building UML Diagrams for the System is to collect as much Airline Reservation data as you can. You’ll need to know how they manage Airline information, processing reservation and distribution of tickets. You must complete all the necessary information in order to provide a quality system for them. Then you’ll apply the data gathered in designing the UML diagrams.
The purpose of building the system is to provide the Airline Admins the easier and efficient way of doing their tasks. And in order to do that, you have to complete the needed diagrams to perfectly furnish your project. Build your project completely and the UML Diagrams will help you and keep you from repeating the development.
Online Airline Reservation System Project UML Diagrams:
Here are the UML Diagrams that composes an Online Airline Reservation System. Each of the UML Diagrams has a major role in achieving a well-developed and functional Airline Reservation System.
- Airline Reservation System Class Diagram | UML
The Class diagram for Online Airline Reservation System shows the structures of information or data that will be handled in the system. These data or information will be represented by classes. Each of the classes will have their attributes in accord to the methods they will use. So the UML Class diagram was illustrated by a box with 3 partitions and the upper part was the name of the class, the middles are the attributes and the bottom is for the methods. The arrows on them represents their relationships in each other.
So the classes that must be made in an Airline reservation would be the reservations, payment, customers, tickets, crews and transaction. The mentioned classes were just general. If you want more complex or wider scope of your Airline reservation system, then you can add your desired classes. You must also include the database on your Class Diagram for your system.
- Airline Reservation System Sequence Diagram | UML
The designed sequence diagram illustrates the series of events that occurs in Airline Reservation System. In this illustration, the actors are represented by a stick man and the transactions or classes are represented by objects. It will give you clear explanation about the behavior of the Airline Reservation System in terms of processing the flow of instructions.
This designed sequence diagram is able to show programmers and readers about the sequence of messages between the actor and the objects.
- Airline Reservation System Activity Diagram | UML
Here’s the UML activity diagram designs of Online Airline Reservation System that you can use for your own Final year Project. The UML activity Diagram is used to show the interaction of the user and the system. By creating it, you’ll be able to see the flaws of the system and you may avoid it once you apply it to the project development. So it is important to have your diagrams designed first before jumping into its development.
Now to create this kind of diagram, you have to determine the processes involve, the users and finalize the behavior of your proposed system.
- Online Airline Reservation System Use Case Diagram
The use cases in the diagram represents the main processes in an Online Airline Reservation system. Then they will be broken down into more specific use cases depending on the included processes of the main use case. In this article you will know the main or general use case of Online Airline Reservation system as well as its specific use cases.
The UML Use Case Diagram is a design used as one of the Methodology on Airline Reservation System development. It represents the main functions or processes of the system as well as the specific processes included. They were also labelled properly to guide programmers and users about the structure of Airline Reservation System.
Another UML Diagrams for Online Airline Reservation System:
- Airline Reservation System DFD Levels 0, 1 and 2 | Best Dataflow Diagrams
As addition to the diagrams that will be a big help in doing your Project is the Dataflow Diagram. It does not belong to the UML diagrams but it also helps in knowing more about the Airline Reservation System. So the DFD serves as an illustration of the systems data handling. As you can see, this DFD design is in level 2, it has levels 0,1 and 2 but the most complex and wider among the 3 is the level 2. So here you will see the main processes included. You may relate these processes form you use case Diagram.
- Then you can also see the actors, or external entities which will be the users of the system. You will also see the database which will be the storage of the data inputs in the system. They will also serve as the source of the outputs from the system. While the arrows with labels are the the data that flows throughout the system. They serve as the inputs and the outputs produce by the system. So the DFD can serve as a behavioral and behavioral diagram at the same time.
- Airline Reservation System ER Diagram | Entity Relationship Diagram
This diagram shows the design of the system’s database. This design could be applied at he back end of the system development. It also serves as the design of the data storage that the system needs. It secures all the essential data in the system and preserves them for important task or when needed.
Tips on Designing the UML Diagram of Online Airline Reservation Project System
To design your UML diagram, you may use platforms and editing tools online. These tools are helpful since they already have the needed symbols to illustrate your diagrams. You just have to plot the included symbols, arrows and labels. The platforms or online tools that you may use are:
As a whole, the UML Diagrams works together to achieve the most desired functions of a Airline Reservation Project System. All of these were designed to guide programmers and beginners about the behavior and structure of the Airline Reservation System.
By completing all the given Diagrams, the Airline Reservation Project System development would be much easier and attainable. So those UML diagrams were given to teach you and guide you through your project development journey. You can use all of the given UML diagrams as your reference, or have them for your project development. The ideas presented in UML Diagrams were all based on Airline Reservation System requirements.
