Explain briefly object modeling , dynamic modeling and functional modeling with the help of suitable diagrams.

In Object-Oriented Analysis and Design (OOAD), three primary modeling techniques are used to capture different aspects of the system: Object Modeling, Dynamic Modeling, and Functional Modeling. These models serve as blueprints for understanding, designing, and implementing a system based on object-oriented principles.

Object Modeling

Object Modeling focuses on representing the system’s objects and their relationships. It highlights the structure and behavior of the system by identifying objects, their attributes, methods, and the associations between them. The object model is generally depicted using class diagrams in Unified Modeling Language (UML).

In an object model, objects are instances of classes, and each class represents a set of objects with shared attributes and behaviors. Associations represent relationships between classes (such as inheritance, aggregation, and association), while operations define how objects interact with each other. The object model emphasizes the static structure of the system, such as how entities are organized and related.

For instance, in an e-commerce system, an object model might include classes such as Customer, Order, Product, and Payment, with relationships like "Customer places Order" or _____ ___ ______ ____ ________ _____ ___ ___ __________ ______.
