· The use case diagram describes the role and the connection between the role and the use case.

It integrates new ideas, new methods and new technologies in the field of software engineering. Its scope is not limited to supporting object-oriented analysis and design, but also supports the whole process of software development from requirements analysis.

The following figure is another Baidu diagram: the figure includes all our use case diagram components: participants, use cases, use case relationships (extension, inclusion, generalization).

Let's review the use scenario of the use case diagram. In the product design stage, we can use the use case diagram to establish an abstract relationship for users, systems and functional services in order to describe the external dynamic characteristics presented by the product.
