Overview
SOLID is an acronym representing five fundamental principles of object-oriented programming and software design. These principles serve as guidelines to create software that is maintainable, scalable, and flexible. Originating from the work of Robert C. Martin (also known as Uncle Bob), the SOLID principles are aimed at improving software development practices by promoting clean code and reducing complexity. Each principle addresses a specific aspect of software design, ensuring that systems remain robust and adaptable to changing requirements.
By adhering to SOLID principles, developers can build software systems that are easier to understand, extend, and refactor, ultimately enhancing the overall quality and longevity of the codebase.
list of the SOLID principles in software design:
Single Responsibility Principle (SRP):
A class should have only one reason to change, meaning it should have only one job or responsibility.
Open/Closed Principle (OCP):
Software entities (classes, modules, functions, etc.) should be open for extension but closed for modification.
Liskov Substitution Principle (LSP):
Objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program.
Interface Segregation Principle (ISP):
Clients should not be forced to depend on interfaces they do not use. Prefer smaller, more specific interfaces over a single large one.
Dependency Inversion Principle (DIP):
High-level modules should not depend on low-level modules. Both should depend on abstractions. Abstractions should not depend on details; details should depend on abstractions.
