How do denormalization techniques in database design impact system performance and data redundancy?
- Degrade system performance and increase redundancy
- Have no impact on system performance
- Improve redundancy but not system performance
- Improve system performance and reduce redundancy
Denormalization in database design involves reducing the level of normalization for performance reasons. While it can improve query performance, it may increase data redundancy and degrade system performance due to extra storage and maintenance overhead.
How can integrating a bug tracking system with a continuous integration pipeline enhance the software development process?
- It hinders code deployment.
- It improves collaboration and issue resolution.
- It increases the number of bugs.
- It slows down the development process.
Integrating a bug tracking system with a continuous integration pipeline enhances software development by improving collaboration, identifying and resolving issues early, and ensuring higher software quality.
What is the main purpose of Configuration Management in software development?
- Accelerating software testing.
- Enhancing user interface design.
- Managing and controlling changes to software.
- Minimizing software development costs.
Configuration management is vital for controlling changes, versions, and ensuring consistency in software development, helping manage the software's lifecycle.
How does effective bug tracking and reporting contribute to the overall quality of a software product?
- It helps in resolving issues promptly.
- It improves code performance.
- It prevents all bugs.
- It speeds up development.
Effective bug tracking and reporting are essential for software quality. They enable the timely identification and resolution of issues, preventing them from becoming severe problems in the final product, which ultimately enhances software quality.
Which Source Code Management tool uses terms like 'commit', 'pull', and 'clone'?
- CVS
- Git
- Mercurial
- Subversion
Git is a popular SCM tool that uses terms like 'commit' for saving changes, 'pull' for fetching updates, and 'clone' for creating a local copy of a repository.
In Software Architecture Design, the _____ pattern helps in minimizing the communication and dependencies between different modules.
- Adapter
- Mediator
- Observer
- Singleton
The Mediator design pattern is used in Software Architecture Design to minimize the communication and dependencies between different modules by centralizing complex interactions and communication.
In a scenario where a project has a tight deadline and minimal initial requirements, how does Agile provide an advantage over traditional SDLC models?
- Agile embraces change and focuses on delivering working software incrementally
- Agile focuses on detailed documentation
- Agile follows a rigid schedule and fixed scope
- Agile prioritizes detailed project planning
Agile provides an advantage in such a scenario by delivering working software incrementally and adapting to changing requirements, making it suitable for tight deadlines and minimal initial requirements.
A team is developing a highly secure banking application. What type of requirements (functional or non-functional) should be prioritized to ensure data security and compliance?
- Both functional and non-functional requirements are equally important for security.
- Functional requirements are more critical for security.
- Non-functional requirements are more critical for security.
- Security requirements are not essential for a banking application.
When developing a highly secure application like a banking system, non-functional requirements take precedence. These include security, compliance, performance, and reliability requirements. While functional requirements define what the system should do, non-functional requirements dictate how well it should do it, especially in terms of security and compliance.
A User Story is a brief description of a feature from an end-user perspective, often used in Agile development.
- Requirement
- Test Case
- Use Case
- User Story
A User Story is a concise description of a feature or functionality from the perspective of an end user. It is a common practice in Agile development to capture user requirements and expectations in a format that is easily understandable by both developers and users.
_____ is a code review technique that involves two programmers working together at one workstation, taking turns being the driver and the observer.
- Code Refactoring
- Code Smell
- Pair Programming
- Unit Testing
The blank should be filled with "Pair Programming." Pair programming is a software development technique where two programmers collaborate on the same task. They work together at one workstation, taking turns as the "driver" and the "observer" to improve code quality.
In Functional Programming, what is the significance of higher-order functions?
- They allow functions to return other functions or take functions as arguments.
- They are used to create object-oriented code.
- They enforce strong typing.
- They only accept one type of data.
Higher-order functions are fundamental in functional programming as they enable functions to be treated as first-class citizens. This allows for functions to be returned from other functions or passed as arguments, which leads to powerful and flexible code constructs, such as mapping and filtering functions.
Which software maintenance model involves making continuous improvements and enhancements to a software product?
- Adaptive Maintenance
- Corrective Maintenance
- Perfective Maintenance
- Preventive Maintenance
Perfective Maintenance involves making continuous improvements and enhancements to a software product to add new features or enhance existing ones, contributing to the product's quality and user satisfaction.
