Object-Oriented Analysis and Design (OOAD) is a software engineering methodology that employs object-oriented principles to model and design complex systems.
It involves analyzing the problem domain, representing it using objects and their interactions, and then designing a modular and scalable solution.
It helps create systems that are easier to understand, maintain, and extend by organizing functionality into reusable and interconnected components.

Important Aspects of OOAD
Here are some important aspects of OOAD:
Object-Oriented Programming: Object-oriented programming involves modeling real-world objects as software objects, with properties and methods that represent the behavior of those objects. OOAD uses this approach to design and implement software systems.
Design Patterns:Design patterns are reusable solutions to common problems in software design. OOAD uses design patterns to help developers create more maintainable and efficient software systems.
UML Diagrams:Unified Modeling Language (UML) is a standardized notation for creating diagrams that represent different aspects of a software system. OOAD uses UML diagrams to represent the different components and interactions of a software system.
Use Cases: Use cases are a way of describing the different ways in which users interact with a software system. OOAD uses use cases to help developers understand the requirements of a system and to design software systems that meet those requirements.
Object-Oriented Analysis
Object-Oriented Analysis (OOA) is the first technical activity performed as part of object-oriented software engineering. OOA introduces new concepts to investigate a problem. It is based on a set of basic principles, which are as follows:
The information domain is modeled:
Lets say you’re building a game. OOA helps you figure out all the things you need to know about the game world – the characters, their features, and how they interact. It’s like making a map of everything important.
Behavior is represented:
OOA also helps you understand what your game characters will do. If a character jumps when you press a button, OOA helps describe that action. It’s like writing down a script for each character.
The function is described:
Every program has specific tasks or jobs it needs to do. OOA helps you list and describe these jobs. In our game, it could be tasks like moving characters or keeping score. It’s like making a to-do list for your software.
Data, functional, and behavioral models are divided to uncover greater detail:
OOA is smart about breaking things into different parts. It splits the job into three categories: things your game knows (like scores), things your game does (like jumping), and how things in your game behave (like characters moving around). This makes it easier to understand.
