Solution
The primary models in object-oriented detailed design are:
d. Sequence diagram and design class diagram
Here's why:
-
Sequence Diagram: This is a type of interaction diagram that shows objects participating in interactions and the sequences of these interactions. It represents the flow of messages in the system and the interaction between objects.
-
Design Class Diagram: This is a static structure diagram that describes the structure of a system by showing the system's classes, their attributes, operations (or methods), and the relationships among objects. It provides a basis for the component and deployment diagrams.
The other options like component diagram, package diagram, and CRC cards are also used in object-oriented design, but they are not the primary models. The component diagram shows how components are wired together to form larger components or software systems. The package diagram depicts the dependencies between the packages that make up a model. CRC cards (Class, Responsibility, Collaborator) are a brainstorming tool used in the design of object-oriented software.
