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.
Conclusion:
The use case diagram is one of the methods that contribute to the Login Page System 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.
