Why is a software review important in the software development process?
- To catch all software bugs before testing
- To eliminate the need for documentation
- To ensure that the project is on schedule
- To find defects, improve quality, and enhance collaboration among team members
Software reviews are essential in the software development process to find defects, improve the quality of the software, and enhance collaboration among team members. They provide an opportunity to identify issues early, discuss potential improvements, and ensure that the software meets the required standards and specifications.
Why is it important to document every change made during the software maintenance phase?
- To pass audits
- To track developers' performance
- To satisfy bureaucracy
- To ensure traceability and maintainability
Documenting every change made during software maintenance is crucial to ensure traceability and maintainability. It helps in understanding why changes were made, which is vital for troubleshooting and future enhancements.
The _____ architecture style involves dividing the system into smaller sub-systems that operate as separate services.
- Monolithic
- Microservices
- Hybrid
- Relational
The Microservices architecture style involves dividing the system into smaller sub-systems that operate as separate services. Each of these services performs specific functions and can communicate with each other, creating a more modular and flexible software architecture.
The Observer design pattern is mainly used in implementing distributed event-handling systems. What is the primary purpose of using it?
- To create objects from a class hierarchy
- To define a family of algorithms
- To maintain a one-to-many dependency between objects
- To provide an interface for creating objects
The primary purpose of the Observer design pattern is to maintain a one-to-many dependency between objects. This means when one object (the subject) changes its state, all its dependents (observers) are notified and updated automatically. It's commonly used in scenarios where you need to implement distributed event-handling systems or maintain consistent data across multiple objects.
Why is Black Box Testing called as such?
- Due to the use of a black box in testing
- Because testers wear blindfolds while testing
- It signifies secrecy in testing
- To represent testing without knowledge of internal structure
Black Box Testing is called so because it symbolizes testing without any knowledge of the software's internal structure, just like a tester is working with a "black box" and doesn't need to see what's inside. This approach emphasizes testing solely based on external behavior.
What is the purpose of using a primary key in a database table?
- To sort data in ascending order
- To uniquely identify each row in the table
- To group related data records
- To define data types for columns
A primary key in a database table is used to uniquely identify each row in the table. It ensures that no two rows have the same values for the primary key, making it a crucial concept for data integrity and efficient data retrieval.
where the developed software meets all specified requirements but fails to fulfill the user's needs in the real-world environment. Discuss the issues related to verification and validation in this context.
- Verification ensures the software meets requirements, but validation ensures it meets user needs
- Verification ensures the software meets user needs, but validation ensures it meets requirements
- Verification and validation are the same
- Neither verification nor validation matters
In this scenario, the issue is related to validation. Verification ensures that the software is built as per the specified requirements, while validation ensures it fulfills user needs. The problem arises because the software may meet its documented requirements but not satisfy what users truly need in the real world. This highlights the importance of both verification and validation in the software development process.
What is the primary purpose of using an API in software development?
- Creating user interfaces
- Handling database operations
- Enabling interoperability between software components
- Generating reports
The primary purpose of using an API in software development is to enable interoperability between different software components. APIs facilitate communication and data exchange between applications, allowing them to work together.
Which of the following best describes the focus of system testing?
- Verifying code syntax
- Testing individual software components
- Evaluating software architecture
- Validating the entire software system
System testing focuses on validating the entire software system, ensuring that it meets the specified requirements and functions as intended. This includes verifying the software architecture, interfaces, and overall functionality.
How does adherence to ISO/IEC 25010 ensure software product quality?
- It guarantees bug-free software
- It covers all aspects of software development
- It defines and measures quality attributes
- It streamlines project management
Adherence to ISO/IEC 25010 ensures software product quality by defining and measuring quality attributes. It provides a framework for assessing and improving various software quality characteristics, including functionality, reliability, performance, and more, thus contributing to overall product quality.
