What is Object Oriented Design (OOD)?

Object-Oriented Design (OOD) is a programming paradigm based on the concept of "objects", which contain data in the form of fields (often known as attributes or properties), and code, in the form of procedures (often known as methods). A key feature of object is that an object's procedures can access and often modify the data fields of the object with which they are associated (objects have a notion of "this" or "self"). OOD is used to design software applications in a modular, reusable, and maintainable way, promoting concepts like encapsulation, inheritance, and polymorphism.
