D - Dependency Inversion Principle | SOLID
The Dependency Inversion Principle (DIP) is the fifth of the five basic principles of object-oriented programming and design, formulated by Robert Martin, known as Uncle Bob.

High level modules should not depend on low level modules; both should depend on abstractions. Abstractions should not depend on details. Details should depend upon abstractions.
I - Interface Segregation Principle | SOLID
The Interface Segregation Principle (ISP) is the fourth of the five basic principles of object-oriented programming and design, formulated by Robert Martin, known as Uncle Bob.

Many client-specific interfaces are better than one general-purpose interface.
L - Liskov Substitution Principle | SOLID
The Liskov Substitution Principle (LSP) is the third of the five basic principles of object-oriented programming and design, formulated by Robert Martin, known as Uncle Bob.
The principle says that
Subclasses should be substitutable for their base classes.
O - Open-Closed Principle | SOLID
The Open-Closed Principle (OCP) is second of the five basic principles of object-oriented programming and design, formulated by Robert Martin, known as Uncle Bob.
The principle says that
Software entities (classes, modules, functions, etc.) should be open for extension, but closed for modification
S - Single Responsibility Principle | SOLID
The Single Responsibility Principle (SRP) is the one of the five basic principles of object-oriented programming and design, formulated by Robert Martin, known as Uncle Bob.
The principle says that
A class should be one, and only one, reason to change.
