OOD stands for Object-Oriented Design, which refers to a programming methodology that revolves around the concept of objects. It is a software design paradigm that promotes the organization of software systems into reusable and modular components, known as objects. These objects encapsulate both data and the functions or methods that manipulate that data.
In OOD, the emphasis is on creating objects that represent real-world entities or concepts, allowing the software to model real-world scenarios more accurately. The objects are designed to interact with each other through well-defined interfaces and communicate by exchanging messages.
One of the key principles of OOD is encapsulation, which ensures that an object's internal data is hidden from external access and can only be accessed through the object's methods. This provides data protection and allows for easier maintenance and modification of the software.
Another fundamental concept in OOD is inheritance, which allows new objects to inherit the characteristics and behaviors of existing objects. This promotes code reusability and facilitates the creation of hierarchies or classifications of objects.
Polymorphism is another vital aspect of OOD, referring to the ability of objects to take on different forms or behaviors depending on the context they are used in.
Overall, OOD provides a framework for designing and building complex software systems by organizing code into reusable objects and promoting concepts such as encapsulation, inheritance, and polymorphism.
