The UML diagrams are categorized into:

• Structural Diagrams

• Behavioral Diagrams

• Interaction Overview Diagrams

• Sequence Diagrams

Behaviour Diagrams include:

• Activity Diagram

• State Machine Diagram

• Use Case Diagram

• Interaction Diagram

• Communication Diagram

1. Class Diagram

2-6. ?????????????????????

• Component Diagram

• Object Diagram

• Composite Structure Diagram

• Deployment Diagram

• Package Diagram

Interaction Diagram include:

• Communication Diagram

• Interaction Overview Diagram

• Sequence Diagram

• Timing Diagram

• Class Diagram

Use Case Diagram gives a ___________________, ___________________ and __________________.

• graphic overview of the actors involved in a system

• different functions needed by those actors

• how these different functions interact

• how these different actors interact

Use Case diagrams are used to analyze the system’s low-level requirements.

(These requirements are expressed through different use cases.)

• True

• False

What are the 3 Main Components of a Use Case Diagram:

• Functional requirements

• Actors

• Relationships between actors and use cases

• Use Cases

Represented as use cases; a verb describing an action.

• Functional requirements

• Actors

• Relationships between actors and use cases

They interact with the system; it can be a human being, an organization or an internal or external application.

• Functional requirements

• Actors

• Relationships between actors and use cases

Represented using straight arrows.
