How to draw a Use Case Diagram?
Time needed: 5 minutes
Here’s the complete guide on how to draw a use case diagram for online shopping cart.

For beginners in the field of designing the diagram, you need first to familiarize the symbols to be used.
- Step 2: Determine the targeted users
The next step is to determine your targeted users. They will be the ones to use your project.
You may ask the users about the typical activities done in online shopping. - Step 3: Analyze the use cases included
The gathered information from the users needs to be evaluated to know the general use cases.
From the general use cases, you will see the sub-cases that are included. But, only have the useful processes and circumstances related to the shopping cart. - Step 4: Plot the Use Case Diagram
To plot the diagram you will need the users, use cases, container (scope), and their indicators (association). You will base the flow of use cases on the evaluated information from the users.
You need to place first the users involved.
Then place the figured use cases included in doing the process.
After that, you will trace the association of the use cases to know the interactions between the user/s and the system.
Finally, put the container in the plotted diagram to separate the objects’ (users and system) scope.

The Use Case Diagram is the starting point for any e-commerce system development.
Conclusion
The use case diagram is one of the methods that contribute to the Online Shopping Cart design and development. It helps developers know the possible inputs and scenarios that the project should process and perform.
Furthermore, you will find out the needed processes and connect them to the other UML Diagrams. The diagram is also applicable in modeling the software’s use cases (processes). It also captures the system’s flow from one process to the next.
