Describe and explain in detail and more specific this system's design process using object-oriented analysis and design techniques. Details about the following items, among others, should be included in explanations: recognizing objects, recognizing characteristics, recognizing linkages, recognizing behaviors, and refining via inheritance. For every items above, must have at least 6 points . iv. Give three concrete example to illustrate how each of these object-oriented concepts can be implemented based on the system's requirements and explain it in detail and more specific . The concepts of abstraction, polymorphism, encapsulation, and inheritance.provide concrete example and explain in detail. Each concept need three examples and detailed explanations
