Online Food Ordering System Project UML Diagrams

ONLINE FOOD ORDERING SYSTEM UML DIAGRAMS – are diagrams formed by the Unified Modeling Languages that acts as the blueprint for the project development. It shows the needed diagrams based in UML to guide you in building your Online Food Ordering System. 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 Food Ordering system should have these UML Diagrams, What are UML Diagrams, How to form them and how they actually work. In this article you will also know the bonus diagrams that will help you in understanding how the Food Ordering System works. Each of these UML Diagrams comes with complete explanation to let you understand its contribution to the Online Food Ordering system.

What are UML Diagrams?

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 use the UML modeling language to create diagrams and 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 Food Ordering 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 Food Ordering 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 Food Ordering System UML Diagrams?

The first thing that you must do before building UML Diagrams for the System is to collect as much Food Ordering data as you can. You’ll need to know how they manage Ordering information, processing orders and distribution of deliveries. 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 Resto or Food Stand Owners 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 its development.

Here are the UML Diagrams that composes an Online Food Ordering System. Each of the UML Diagrams has a major role in achieving a well-developed and functional Online Food Ordering System.

Online Food Ordering System Class Diagram
The Class diagram for Online Food Ordering 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 Ordering are the dishes, orders, customers, deliveries, payment, menu and the admin or crew. The mentioned classes were just general. If you want more complex or wider scope of your Online Food Ordering system, then you can add your desired classes. You must also relate the database on your Class Diagram for your system.
Food Ordering System Use Case Diagram
The use cases in the diagram represents the main processes in an Online Food Ordering system. Then they will be broken down into more specific use cases depending on the included processes of the main use case. Each of these use cases explains how the system handles the actions or scenarios requested by the user.

The UML Use Case Diagram is a design used as one of the Methodology on Online Food Ordering 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 Online Food Ordering System.
Online Ordering System Sequence Diagram
The designed sequence diagram illustrates the series of events that occurs in Online Food Ordering 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 an Online Food Ordering 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.
Online Food Ordering System Activity Diagram | UML
Here’s the UML activity diagram design of Online Food Ordering 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 Ordering System ER 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.

Food Ordering System DFD Levels 0, 1 and 2
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 Online Food Ordering 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 from your 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 structural diagram at the same time.

Tips on Designing the UML Diagram of Online Food Ordering 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:
• Lucidchart
• Creately
• Smartdraw
• Edrawmax
• Canva

Conclusion:

As a whole, the UML Diagrams works together to achieve the most desired functions of an Online Food Ordering Project System. All of these were designed to guide programmers and beginners about the behavior and structure of Online Food Ordering System.

By completing all the given Diagrams, the Online Food Ordering 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 Online Food Ordering System requirements.
