In legacy systems, data and functionality are often tightly intertwined, making it challenging to scale or adapt to modern, internet-based applications. Object-Oriented (OO) programming provides a solution by encapsulating data and behavior into reusable, modular objects. Today, one of the most fascinating areas of software development is the integration of legacy systems with internet-based platforms, utilizing objects in OO programming to bridge the gap between old and new technologies.

But what exactly is an object? At its core, an object is a building block of an OO program. A program that employs OO principles is fundamentally a collection of objects working together. For instance, in a corporate system, there may be objects that represent the company’s employees. Each of these objects encompasses both data and behavior, which we will explore further.

Objects have become integral to both our personal and professional information systems (IS), and they cannot be overlooked. You likely interact with objects daily without even realizing it—whether in your car, on your cell phone, while using digital TV, or in many other everyday situations.

In this series of blog posts, we will discuss the following areas:

Objects: The Core of OOP Understanding the Fundamental Units of Object-Oriented Design

Classes: Crafting Blueprints for Objects Defining Structure and Behavior in Your Programs

Inheritance: Unlocking Reusability How Inheritance Enhances Code Efficiency and Hierarchy

Polymorphism: Embracing Flexibility Creating Dynamic Interactions and Adaptable Code

Encapsulation: The Art of Data Protection Ensuring Data Security and Streamlining Object Interaction

Each post will delve into these key concepts, providing insights and practical examples to enhance your understanding of Object-Oriented Programming.
