SOEN Chapter 5 Intro

What is the main purpose of models in the requirements engineering process?

• To write code.

• To create abstract views of the system.

• To avoid system testing.

• To eliminate stakeholder communication.

How do models benefit the analysis of existing systems?

• They identify both the strengths and weaknesses of the system.

• They ensure the system is free from bugs.

• They reduce the need for system testing.

• They eliminate the need for documentation.

Which perspective in system modeling represents the system's context or environment?

• Structural perspective

• Behavioral perspective

• Interaction perspective

• External perspective

Which perspective in system modeling focuses on the organization and structure of the system's data?

• Structural perspective

• Behavioral perspective

• Interaction perspective

• External perspective

Which perspective in system modeling focuses on how the system responds to events?

• Structural perspective

• Behavioral perspective

• Interaction perspective

• External perspective

Which perspective in system modeling represents the interactions between the system and its environment or between components of the system?

• Structural perspective

• Behavioral perspective

• Interaction perspective

• External perspective

Which diagram illustrates the interactions between actors, the system, and components?

• Activity diagram

• Use case diagram

• Sequence diagram

• Class diagram

In an activity diagram, how is the start of a process represented?

• A filled circle inside another circle

• A rectangle with rounded corners

• A filled circle

• An arrow

In a use case diagram, how are human interactions or external systems represented?

• By rectangles

• By stick figures

• By filled circles

• By arrows

In a sequence diagram, how is the lifetime of an object represented?

• By arrows between objects

• By rectangles on dotted lines

• By stick figures

• By filled circles
