Object-Oriented Analysis and Design (OOAD)

Object-Oriented Analysis and Design (OOAD) is a method used to create software systems by modeling real-world entities as "objects" with properties and behaviors. During analysis, it identifies what the system needs to do by understanding these entities and their relationships. During design, it determines how to organize and implement these objects effectively within the software, ensuring the system's components work together logically. Think of it as designing a detailed blueprint and then building with blocks that represent real-world items, making complex systems easier to develop, maintain, and understand.
