Questions and Answers

Why would you probably not maintain the system that asks the user for their birth date and prints out the day of the week for their next birthday?

It would not have any bugs

It is not particularly useful (correct)

It is too complex to maintain

It is not particularly inconvenient to execute

What is the main reason for the unlikelihood of unsolved bugs in the program that asks for the user's birth date?

It uses a reliable programming language

It is not a software program

It has been thoroughly tested

It is too simple to have bugs (correct)

Why is it unlikely that you would need to execute the program again if it fails?

It rarely fails

It can fix itself automatically

It has no critical impact if it fails (correct)

It is easy to troubleshoot and fix

Study Notes

System Maintenance

Probability of maintaining a system that asks for a user's birth date and prints the day of the week for their next birthday is low due to its simplicity.
The system has a low likelihood of unsolved bugs because it performs a single, straightforward task.

Program Execution

If the birth date program fails, it is unlikely that re-execution would be necessary.

System Complexity

A system for storing customers and products in a database and providing a GUI is more complex than the birth date system due to its multiple components and interactions.

Object-Oriented Analysis and Design

Analysis

The primary focus of analysis in object-oriented analysis and design is to identify the problem domain and its requirements.
Analysis is usually performed by a system analyst or business analyst.

Design

The main focus of design in object-oriented analysis and design is to create a solution that meets the identified requirements.

Roles and Responsibilities

An architect plays a key role in object-oriented design and analysis, overseeing the overall system architecture and design.

Design Patterns

Design patterns represent proven, reusable solutions to common problems in object-oriented analysis and design.
Understanding design patterns is important to ensure a robust and maintainable system.

Program Modularization

A key advantage of modularizing a program is that it allows for easier maintenance, updates, and bug fixing.

Program Quality

It is essential to remove bugs and make improvements in a program that might be sold to a customer to ensure customer satisfaction and maintain a company's reputation.

Large-Scale Systems

An unavoidable aspect of large-scale systems is their inherent complexity.

Software Development

During the requirements capture/determination stage of software development, the focus is on gathering and understanding the user's needs and requirements.
