Module 1.1: Objects and Object Models

Object

A fundamental, self-contained unit that represents a real-world or abstract entity. Contains attributes that describe its characteristics and behaviors that define its actions.

Model

An idea or concept that represents a set of entities. It serves as a general representation from which individual instances can be identified.

Instance

A realization of a particular model or class. Represents one specific object belonging to a general category

Object Model

A representation of an object that identifies its attributes or state and its possible behaviors. It describes what information an object contains and what actions it can perform.

Attributes

The characteristics or properties that describe an object. Represent information associated with an object, such as its name, color, age, or balance.

State

The current condition or values of an object's attributes. An object's state can change over time as it performs different actions.

Behavior

The possible actions that an object can perform. May change an object's state, retrieve information about its state, or affect another object's state. In Java, they are represented by methods.

Abstraction

The process of representing an entity using its essential characteristics and behaviors while leaving out unnecessary details.

Anthropomorphic

Describes the treatment of objects as entities that have their own characteristics and can perform actions.

Basic Data Manipulation Operations
