What are the key design principles in software development?

The key design principles include modularity, encapsulation, abstraction, and separation of concerns. Would you like to know more about any specific principle?

Can you explain modularity?

Modularity refers to the design principle of breaking down a system into smaller, manageable, and independent modules. Each module can be developed, tested, and maintained separately.

How does encapsulation fit into this?

Encapsulation is about bundling the data and methods that operate on that data within a single unit or class. It restricts direct access to some of the object's components, which helps to prevent unintended interference and misuse.

What about abstraction?

Abstraction simplifies complex systems by hiding unnecessary details and exposing only the essential features. It allows developers to focus on interactions at a higher level.

Can you give an example of separation of concerns?

Sure! In a web application, separating the user interface, business logic, and data access layers allows for easier maintenance and scalability. Each layer can evolve independently.
