Study Notes
Use Case Diagram
- A use case is a sequence of actions that provide something of measurable value to an actor and is represented by a horizontal ellipse.
- A use case describes a specific interaction between actors and the system.
Actors
- An actor is a person, organization, or external system that plays a role in one or more interactions with the system.
- Actors are represented by stick figures in use case diagrams.
Associations
- Associations between actors and use cases are indicated by solid lines in use case diagrams.
- An association exists whenever an actor is involved with an interaction described by a use case.
System Boundary Boxes
- System boundary boxes are optional rectangles drawn around the use cases to indicate the scope of the system.
- They help to clarify the boundaries of the system.
Packages
- Packages are UML constructs that enable organizing model elements (such as use cases) into groups.
- Packages are depicted as file folders and can be used on various UML diagrams, including use case diagrams and class diagrams.
- They help to organize and structure the model elements.
