Document Summary
A uml use-case diagram is a model that allows the user to understand what the position of each member is. It can also be described as the functionality of a system. The model allows the user to see all the functions of the system that is available to the user. According to the model, it only has 4 major elements: the actors, the system, the use cases, and the relationships. The actors are the ones who interact with the system. The system is the system that the user is using, which acts as the whole diagram. The use-cases are known as the performance of the system, knowing what to do. The relationships are the lines that connect the actors with the use-cases. The model is useful to represent the functionality of the system, allowing the users to take a quick glance to see the system"s functionality with a high-level description of its performance.
