Use case diagrams specify the events of a system and their flows. But use case diagram never describes how they are implemented. Use case diagram can be imagined as a black box where only the input, output, and the function of the black box is known. These diagrams are used at a very ...
AUML use case diagramis the way to model system requirements for a new software system being developed. They show the expected view and response of the design from the end user's point of view. Use a case diagram is an effective technique for communicating system behavior from the end user...

A use case diagram is a type of behavioral diagram defined by theUnified Modeling Language(UML). It consists of use cases, actors, and the relationships between them. Here are the key components: Use Case: Represents a specific functionality or service that the system provides to the user. ...
描述用例行为(Describing Use Case Behaviors) 用例行为(behaviors) 可以用自然语言文本(不透明行为)来描述,这是目前常见的做法,也可以通过使用UML 行为图(behavior-diagram) 来表示特定行为,如 活动(activity), 状态机(state machine), 交互(interaction)。
Use-case diagrams illustrate and define the context and requirements of either an entire system or the important parts of the system. You can model a complex system with a single use-case diagram, or create many use-case diagrams to model the components of the system. You would typically dev...
(a cleansing engineer and service person) represent any external object that interacts with the system. Uses cases reside inside the system boundary, and actors reside outside. Association lines show relationships between the use cases and the actors. The following use-case diagram demonstrates these...
