Software Engineering

What is the main purpose of requirements analysis in software development?

• To write the actual code

• To design the user interface

• To specify software's operational characteristics

• To test the software

Which type of model represents object-oriented classes and how they collaborate to achieve system requirements?

• Data models

• Flow-oriented models

• Class-oriented models

• Scenario-based models

What do flow-oriented models represent in software development?

• User interactions with the system

• Data transformations in the system

• The information domain of the problem

• Object-oriented classes and collaborations

What are the primary objectives that the requirements model must achieve?

• Describe company background

• Describe what the customer requires, establish a basis for software design, define requirements that can be validated

• Define software limitations

• Establish project deadlines

Who is responsible for defining, categorizing, and preparing analysis patterns and classes for future projects?

• Domain analysts

• Software developers

• Project managers

• End users

What is the goal of domain analysis in software engineering?

• To complicate the software development process

• To create unique solutions for each project

• To limit reuse of common patterns

• To find or create broadly applicable analysis classes and patterns for reuse

Which of the following best describes the role of a domain analyst in software engineering?

• A discoverer and definer of analysis patterns and classes for reuse

• A master toolsmith

• A coding specialist

• A project manager

What is the main difference between structured analysis and object-oriented analysis?

• Structured analysis focuses on data objects and processes separately, while object-oriented analysis focuses on classes collaborating with each other

• Object-oriented analysis models data objects with attributes only, while structured analysis models processes only.

• Structured analysis considers data objects as processes, while object-oriented analysis does not focus on data manipulation.

• Structured analysis uses UML and the Unified Process, while object-oriented analysis does not.

How does class-based elements in the requirements model differ from scenario-based elements?

• Class-based elements depict how data objects flow through the system, while scenario-based elements model the operations applied to objects.

• Class-based elements show specific sequences of activities, while scenario-based elements model how data objects are transformed.

• Class-based elements focus on user interactions, while scenario-based elements model data objects.

• Class-based elements model relationships between objects and collaborations between classes, while scenario-based elements depict user interactions

What do behavioral elements in the requirements model depict?

• Collaborations between classes in the system

• Hierarchical relationships between data objects

• The specific sequence of activities as the software is used.

• How external events change the state of the system or classes.
