Ict2622 - Requirements Models

A System Sequence Diagram (SSD) is a type of diagram that represents the interactions between an external actor and a system. It shows the sequence of messages exchanged between the actor and the system in order to achieve a specific goal. This diagram is used to model the behavior of a system from an external perspective and is often used in the early stages of software development to capture system requirements and define system behavior.

A use case diagram is a type of diagram that represents the interactions between actors (users or external systems) and a system. It illustrates the different use cases or functionalities of the system and the relationships between them. In a use case diagram, actors are represented as stick figures, and use cases are represented as ovals or rectangles. This diagram helps to understand the system's behavior from a user's perspective and is commonly used in software development to capture the functional requirements of a system.

The given answer is "Activity diagram and use case description". An activity diagram is a graphical representation of the flow of activities within a system or process, showing the sequence of actions and decisions. Use case descriptions, on the other hand, provide detailed explanations of the interactions between actors and the system, describing the specific steps and conditions involved. Together, these two components help to illustrate the behavior and functionality of a system in a clear and comprehensive manner.

The domain model class diagram is used in the Design Class Diagram. The Design Class Diagram is a diagram that represents the structure and organization of the classes in a system, including their attributes, methods, and relationships. It is used to depict the static design of the system and how the classes interact with each other. The domain model class diagram, on the other hand, represents the conceptual classes and their relationships in the domain of the problem being solved. Therefore, the domain model class diagram serves as a basis for creating the Design Class Diagram.

The diagrams that fall under the requirements model are the Domain model class diagram, Use case diagram, and System Sequence Diagram. These diagrams are used to capture and represent the requirements of a system. The Domain model class diagram provides a visual representation of the classes and their relationships in the system's domain. The Use case diagram depicts the interactions between actors and the system, showing the system's functionality. The System Sequence Diagram illustrates the sequence of interactions between actors and the system to accomplish a specific use case. These diagrams are essential for understanding and documenting the requirements of a system.

Use case diagrams are used in the Interaction Diagram section of the design model. Interaction diagrams show how different elements of a system interact with each other to achieve a specific goal or behavior. Use case diagrams specifically depict the interactions between actors (users or external systems) and the system itself, illustrating the different use cases and their relationships. Therefore, the correct answer is Interaction Diagram.
