Which of the following best describes the purpose of class diagrams in UML?

• To represent the sequence of operations in a system.

• To show the classes in a system and the associations or relationships between them.

• To illustrate the user interface design of the system.

• To depict the overall deployment of system components.

What is the structure of class diagrams used in database design?

• Class name, attributes, and methods.

• User interactions and workflows.

• Physical hardware layout.

• Relationships between users.

What does generalization represent in class diagrams?

• A detailed description of class methods.

• The relationship between users and the system.

• The reuse of characteristics from general classes, focusing on differences.

• The sequence of operations in a system.

What does aggregation represent in class diagrams?

• A class that inherits from another class.

• A composition of one object made up of other objects.

• A sequence of operations within a system.

• A link between unrelated objects.

What do state diagrams represent in UML?

• The classes and their relationships.

• The sequence of system operations.

• The states of a system and transitions between them.

• The physical layout of system components.

In a state diagram, how are the start and end points of a system represented?

• By rectangles.

• By diamonds.

• By arrows.

• By filled circles.

What do context models typically show in a system?

• Detailed user interactions with the system.

• Relationships between different automated systems.

• The environment, including other automated systems, without specifying relationships.

• The flow of data between system components.

Why is modeling interactions important in system design?

• It helps in designing the database schema.

• It assists in identifying user requirements.

• It outlines the physical layout of the system.

• It determines the network infrastructure.

What do system organization models show?

• Components and their relationships.

• Database schema.

• User interface layout.

• User interaction sequence.

What do behavioral models illustrate?

• The static structure of a system.

• The system's behavior during execution.

• The physical hardware configuration.

• The user interface design.
