Introduction To UML

The UML is the standard language for visualizing,

specifying, constructing, and documenting the

artifacts of a software-intensive system.

It can be used with all processes, throughout thedevelopment life cycle, and across different

implementation technologies.

The standard for OO systems

hat is Unified Modeling Language?

Introduction To UML

The UML combines the best of the bestfrom:-

Data Modeling concept

(Entity Relationship Diagrams) Business Modeling

(work flow)

Object Modeling

Component Modeling

What is UML Represent ?

Introduction To UML

Is an open standard.

Supports the entire software developmentlifecycle.

Supports diverse applications areas. Is based on experience and needs of the user

community.

Supported by many tools.

The Value OfUnified Modeling Language

Object-Oriented Methodology

A program will typically consist of objects that

cooperate to solve a task.

An object will typically have attributes (data) and

methods (behavior), this defines the state of theobject and the manner in which the object operate.

Objects communicate by sending messages to each

other. Sending a message to an object is the same

as calling a method of the object.

Hint To know About

Object-Oriented Methodology

-- ClassClass: A description of a set of objects that sharethe same attributes, operations, relationships, and

semantics.

-- ObjectObject: A concrete manifestation of anabstraction; an entity with a well defined boundaryand identity that encapsulates state and behavior;

an instance o f a class.
