• File Paths: Storing the path to the image file on the server, allowing for efficient storage and retrieval.

Object-Oriented Programming (OOP) is a paradigm based on objects and classes, promoting code reusability and modularity.

• Encapsulation: Bundling data and methods that operate on the data within one unit (e.g., a class).

• Inheritance: Mechanism to create a new class using properties and methods of an existing class (e.g., a 'Dog' class inheriting from an 'Animal' class).

• Polymorphism: Ability to present the same interf...read more
