SOLID Principles

Applying SRP in Larger Systems

In larger systems, SRP can be applied by splitting responsibilities across multiple classes or services. For example, in a typical web application, you might have:

  • Controllers: Handle HTTP requests and responses.
  • Services: Contain business logic.
  • Repositories: Handle data access.
  • Models: Represent the data.

Each layer or component has a single responsibility, making the system more modular and easier to maintain.

Conclusion

The Single Responsibility Principle is a foundational concept in software design that promotes writing classes and methods with only one responsibility. Adhering to SRP results in code that is easier to understand, maintain, test, and reuse. By carefully designing classes and methods to adhere to SRP, you can create more robust and flexible software systems.
