📖 1. Object-Oriented Programming

🔑 Key Concepts & Definitions

• Object-Oriented Programming (OOP): A programming paradigm that organizes software design around "objects"— data structures that contain both data fields and methods. This approach shifts focus from procedures (functions) to modeling real-world entities, making complex systems more manageable (SOURCE).
• Objects as Data Structures: Entities that encapsulate data fields (attributes) and methods (functions) which operate on that data, representing real-world or conceptual items within a program (SOURCE).
• Shift from Procedure-Oriented to Object-Oriented Design: Transition in programming methodology from a focus on functions and global data to a focus on objects that encapsulate data and behavior, promoting modularity, reusability, and security (SOURCE).
• Modeling Real-World Entities with Objects: The process of representing real-world items (like books, users, or transactions) as objects within a program, enabling intuitive and natural mapping between software and real-world systems (SOURCE).
