In the field of software engineering, understanding architecture design principles is crucial. These principles guide developers in creating scalable, maintainable, and efficient systems.

Key Principles

  1. Single Responsibility Principle (SRP): A class should have only one reason to change. This principle ensures that each class has a clear, well-defined responsibility.
  2. Open/Closed Principle (OCP): Software entities should be open for extension but closed for modification. This allows the system to be extended without modifying its existing code.
  3. Liskov Substitution Principle (LSP): Objects of a superclass should be replaceable with objects of a subclass without affecting the correctness of the program.
  4. Interface Segregation Principle (ISP): Many client-specific interfaces are better than one general-purpose interface. This principle ensures that interfaces are focused on specific client needs.
  5. Dependency Inversion Principle (DIP): High-level modules should not depend on low-level modules. Both should depend on abstractions. This principle encourages the use of interfaces and abstract classes.

Real-World Example

Consider a banking application. One of the key components is the Account class. The Account class should adhere to the Single Responsibility Principle, focusing solely on account-related functionalities.
