The users that are essential in creating an activity diagram for Online Food Ordering System would be the Resto Owner and the Customers. 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. So you should be aware that your system must be user-friendly and effective for its users.

What is a Food Ordering System Activity Diagram?

To have a clear understanding about it, let me tell you its purpose and role. The Online Food Ordering System must have an activity diagram so that the programmers would have a basis on how should the software approach its users.

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 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 Online Food Ordering 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 Online Food Ordering System.

This design is to explain and inform readers or users that the system provides security for the important transaction records and can only be accessed by authorize personnel.

You should be informed that the diagram can be modified to achieve your desired system behavior. You can also create your unique system function to justify all of your clients needs. And if you want, you can copy all the ideas presented here so you won’t need to create a new one.

You may also merge with other diagrams if you want to make you activity diagram general. But you just have to make sure that the specificity is still there so your readers and system users understands the blueprint for online food ordering system development.


It is essential for you to know the diagrams used to design and develop the Online Food Ordering System. That is because you cannot perfectly create a fully-functional system without it. But if you create this activity diagram, you will know the possible inputs and scenarios that the system should process and perform. Not only that, you will find out the needed processes and connect them to the other UML Diagrams.

By completing the Activity Diagrams per module or per processes, you will easily achieve your desired system.
