SOLID Principles
The SOLID principles are a set of guidelines for designing software that is easy to manage and extend. They were introduced by Robert C. Martin and are often used to guide software development practices. Here's a brief overview of each principle:
- Single Responsibility Principle (SRP):
A class should have only one reason to change, meaning it should have only one responsibility or job.
- Open/Closed Principle (OCP):
Software entities (classes, functions, modules, or methods) should be open for extension but closed for modification.This allows you to add new functionality without changing existing code.
- Liskov Substitution Principle (LSP):
Subtypes must be substitutable for their base types without altering the correctness of the program. Essentially, derived classes should extend the behaviour of a base class without changing its expected behaviour.
- Interface Segregation Principle (ISP):
A class should not be forced to implement the interfaces it doesn't use. This means creating smaller, more specific interfaces, rather than a large, general one.
- Dependency Inversion Principle (DIP):
High-level modules should not depend on low-level modules; both should depend on abstractions (e.g., interfaces). Additionally, abstractions should not depend on details, but details should depend on abstractions.
These principles help in designing systems that are more flexible, easier to maintain, and scalable.
Let us understand each of the above principles in depth in the below mentioned blogs.
