OOAD Interview Questions and Answers will guide that Object-oriented analysis and design (OOAD) is a software engineering approach that models a system as a group of interacting objects. Each object represents some entity of interest in the system being modeled, and is characterised by its class, its state (data elements), and its behavior. So learn OOAD with the help of this OOAD Interview Questions with Answers guide
