UML_OOPs

What does UML stand for?

• User Management Library

• Unified Modelling Language

• Unified Modeling Logic

• Universal Markup Language

What is the purpose of a Use Case diagram?

• To identify the requirement of a system

• To visualize hardware topology of a system

• To represent the flow of messages in the system

• To model the dynamic behaviour of a system

What is the primary difference between class diagrams and interaction diagrams?

• Class diagrams represent the dynamic behaviour of a system while interaction diagrams represent the static aspects

• Class diagrams describe the structure while interaction diagrams describe the behaviour

• Class diagrams emphasize the flow of messages while interaction diagrams emphasize the structural aspects

• Class diagrams focus on organization over timing while interaction diagrams focus on message flow

What is the purpose of a Collaboration Diagram?

• To show the relationship between the objects in a system

• To model the instances of things contained in class diagrams

• To model the flow of messages in the system

• To visualize the static deployment view of a system

What is the main goal of developing UML?

• To create a truly industry standard programming language

• To focus on the structural aspects of a system

• To model software systems only

• To define a general-purpose modelling language

What is the purpose of an Activity Diagram?

• To visualize the real-time data of a system

• To represent the static deployment view of a system

• To model the instances of things contained in class diagrams

• To show the flow from one activity to another in a system or process

What is the primary benefit of using a Communication Diagram?

• Visualizes the hardware topology of a system

• Emphasizes how lifelines connect

• Provides an added emphasis on timing over organization

• Focuses on message flow

What is the primary objective of an Interaction Diagram?

• To model the static deployment view of a system

• To visualize hardware topology of a system

• To describe the organization of physical software components

• To monitor the dynamic behaviour of a system

What is the purpose of a Timing Diagram?

• To show the relationship between the objects in a system

• To visualize the real-time data of a system

• To model the flow of messages in the system

• To depict the state of a lifeline at any instance in time

What is the purpose of a Sequence Diagram?

• To show the relationship between the objects in a system

• To model the instances of things contained in class diagrams

• To model the flow of messages in the system

• To depict the sequence of messages exchanged between objects in a system
