Why is it unlikely to have unsolved bugs in a program that asks for the user's birth date and prints out the day of the week for their next birthday?
Why is it unlikely to have unsolved bugs in a program that asks for the user's birth date and prints out the day of the week for their next birthday?
- The user input is limited and hence has fewer chances of resulting in bugs.
- The program is designed to be error-free from the beginning.
- The problem is simple and straightforward, leading to fewer bugs. (correct)
- The system employs advanced bug-detection algorithms.
Why is it stated that you probably wouldn't maintain a small-scale system that asks for the user's birth date and prints out the day of the week for their next birthday?
Why is it stated that you probably wouldn't maintain a small-scale system that asks for the user's birth date and prints out the day of the week for their next birthday?
- The system is not deemed important enough to justify regular maintenance. (correct)
- The program is designed to automatically update itself when needed.
- There are no bugs to be fixed, so maintenance is unnecessary.
- The system is expected to function perfectly without any maintenance.
What does the author imply by stating 'You could probably write the program alone' in reference to the small-scale system?
What does the author imply by stating 'You could probably write the program alone' in reference to the small-scale system?
- The program can be written without any specific skills or knowledge.
- The program is simple enough to be developed by a single individual. (correct)
- It is necessary to work on the program without any external assistance.
- The program does not require any coding expertise to develop.

Study Notes
- Object-Oriented Analysis & Design is a process of building software systems by first analyzing the user requirements (functional and non-functional), then designing the software structure to meet those requirements
- Analysis is typically performed by a systems analyst, who focuses on the software's functionality as a black box, without caring about its internal workings
- Design is typically performed by an architect or designer, who focuses on the overall structure of the software, including distribution of components, modularity, and non-functional requirements
- Design patterns are recurring themes in software systems and can provide common solutions to common challenges
- The need for design exists to create clear and effective structures for software systems
- Developing small-scale systems may not require formal design, but for medium and large-scale systems, formal design is essential to manage complexity and maintainability
- The Unified Process is a software development methodology that emphasizes iterative development and risk reduction, with significant overlap between phases
- The Unified Process includes requirements capture/determination, requirements analysis, system design, class-level design, user interface design, data design, implementation, testing, and iteration
- Iterations involve revisiting earlier phases and adding/updating components, typically taking 1-8 weeks to complete and aiming for minor milestones before moving on to the next iteration.
- The Waterfall Model is an alternative software development process where phases are mutually exclusive and motion is unidirectional, leading to poor use of human resources due to waiting times.
