1. Modularity: A good program design should be modular, meaning that it is composed of smaller, independent modules that can be easily combined and reused. This makes the program easier to understand, maintain, and modify.
2. Cohesion: Each module in a good program design should be cohesive, meaning that it performs a single, well-defined task. This makes the program easier to understand and maintain.
3. Coupling: The modules in a good program design should have low coupling, meaning that they are not tightly connected to each other. This makes the program more flexible and easier to change.
4. Extensibility: A good program design should be extensible, meaning that it can be easily modified to add new features or functionality. This makes the program more adaptable and future-proof.
5. Reusability: The modules in a good program design should be reusable, meaning that they can be used in multiple programs. This saves time and effort in the development process.
6. Simplicity: A good program design should be simple, meaning that it is easy to understand and maintain. This makes the program more reliable and trustworthy.
7. Efficiency: A good program design should be efficient, meaning that it uses resources wisely and does not waste time or space. This makes the program faster and more responsive.
8. Reliability: A good program design should be reliable, meaning that it works correctly and consistently. This makes the program more dependable and user-friendly.
9. Maintainability: A good program design should be maintainable, meaning that it is easy to fix bugs and make changes. This makes the program less expensive to maintain and keeps it up-to-date.
Conclusion
A good program design is essential for software that is high-quality, reliable, and maintainable. The characteristics discussed above can help you create programs that are easy to understand, develop, and use.
