What is modular design in software development?

What is modular design in software development?

Modular design in software development refers to creating software systems that are divided into separate, interchangeable modules. Each module handles a specific functionality, making the system easier to manage, update, and scale.

What are the benefits of using modular design?

The benefits include improved maintainability, easier debugging, enhanced collaboration among teams, and the ability to reuse modules across different projects.

Can you give me an example of modular design in a real-world application?

Sure! A great example is the use of microservices in web applications, where each service is a module that performs a specific function, like user authentication or payment processing.

How does modular design affect software testing?

Modular design simplifies testing because each module can be tested independently. This isolation helps identify issues more quickly and ensures that changes in one module don't affect others.
