The use case diagram describes a functional unit provided by the system. The purpose of the use case diagram is to help the development team understand the functional requirements of the system in a visualized manner, including "Roles" based on basic processes (actors, other entities that interact with the system) relationship and the relationshi

The key to dealing with object-oriented problems is modeling. Modeling can abstract many important details in the complex world. Many Modeling tools encapsulate UML (that is, the Unified Modeling Language). This course aims to show the highlights of UML.

9. use case diagram: 1. Definition: a dynamic view composed of actors, use cases, and their relationships used to describe system functions is called a use case diagram.
2. Composition: ① participants (executors)
1) definitions of participants: Participants refer to the abstraction of external entities of people, systems, or classes that exist outside the system and interact directly with the system. A part
first, the conceptThe interaction diagram describes the dynamic cooperative relationship between objects and the order of behavior in the process of cooperation. Interaction diagrams are often used to describe the behavior of a use case, to show the objects involved in the use case and the message delivery between those objects, i.e. the implementation of a use case.
there are two forms of interaction graph, Order
Object-oriented modelObject-oriented model is a model that uses UML (Unified Modeling Language) to describe the system structure, and it realizes the working state of the system from different angles. These graphs facilitate information exchange between users, managers, system analysts, developers, testers, and other personnel.

In object-oriented dynamic modeling, four types of graphs are used to establish behavior interaction between entities: Stage divisor, sequence divisor, and communication divisor ), activity digraphs, where, "Sequence Chart"And"Collaboration diagram"Similar messages are expressed.

Class diagrams and sequence diagrams are directly associated with program code in software system design. To be precise, program code is directly generated by class diagrams, A Sequence Chart can define a class chart method. The use case diagram is used to describe system functions and has no direct relationship with the sequence diagram.
