Description: Object Oriented Design (OOD) is a methodology used in software engineering to structure a system as a collection of interacting objects, each representing real-world entities or concepts. It emphasizes modularity and reusability, making complex software easier to manage and evolve. By modeling software around objects rather than actions, developers can create systems that are more intuitive and aligned with real-world scenarios.Encapsulation is a key principle of OOD that restricts direct access to an object’s data and exposes only necessary functionalities through methods. This approach protects the integrity of the object’s internal state, reduces complexity, and enhances maintainability. Encapsulation also promotes clear interfaces, allowing developers to modify the internal workings of a class without affecting external code.Inheritance allows one class to derive properties and behaviors from another, enabling code reuse and hierarchical organization. Through inheritance, common functionality can be defined in a base class and shared across multiple derived classes, reducing redundancy. It also facilitates polymorphic behavior, where objects of different classes can be treated uniformly if they share a common base class.Polymorphism enables objects to take on multiple forms depending on the context, often through method overriding or interface implementation. This allows the same operation to behave differently on distinct classes, enhancing flexibility and scalability in software design. Polymorphism, combined with inheritance, allows developers to write more generic and reusable code.Design Patterns provide standardized solutions to common software design problems. Patterns such as Singleton, Observer, and Factory Method encapsulate best practices and offer templates for solving recurring challenges in OOD. Using design patterns improves code readability, maintainability, and reduces the risk of introducing bugs.UML Modeling is used in OOD to visually represent the stru
