An Overview Of UML

• Purpose of creating UML

The intention behind formulating UML is to design, describe and specify an existing document or an entirely new business process. But it is not limited to this boundary; it is used to model non-software systems as well like process flow in manufacturing unit etc. UML are not only made for developers. Anyone from business users to common people who desires to understand the system can use the system. 

• A conceptual model of UML

Conceptual model is what you called a model made of concepts and their relationships. In context of UML, conceptual model is the first step before drawing UML diagrams. It helps to understand in the real world how they have relations with each other. The conceptual model of UML can be perceived if you understand the following major elements first, says our UML assignment help Australia experts.
1. UML building blocks
2. Rules to connect the building blocks
3. Common mechanism of UML

• Concepts of object-oriented

UML is usually referred to as the successor of object-oriented analysis and design. UML diagrams are powerful enough to represent all concepts exits in object-oriented analysis and design. So it is important that you understand object-oriented (OO) concepts at first and then focus on learning UML.

Our UML assignment help Australia experts describe the basic concepts of OO world:
1. Objects: It consists of both data and methods that control the data. It is the basic building of OO concepts.
2. Class: It describes an object, more precisely a blue print of an object.
3. Abstraction: It reflects the behavior of real world entity.
4. Encapsulation: It is a mechanism that binds the data together and hides them from outside world.
5. Inheritance: It is a method of making new classes out of old ones.
6. Polymorphism: It depicts the mechanism to exist in different forms.

• OO analysis and design

OO analysis can be described as investigation and to be more specific it is the mechanism of investigating objects. The purpose of OO analysis and design can be described simply under these points:
1. Identifying the objects of a system
2. Identifying their relationships
3. Make a design which can be converted to executables using OO languages.

These are three basic steps of implementing and applying OO concepts.

OO Analysis: During the analysis period, our UML assignment help Australia experts indicate that objects are identified and described in proper way. Proper way means objects should be identified with responsibilities so that responsibilities can be collaborated and fulfill the purpose of their existence in system. 

OO Design: In this next stage, the objects are collaborated according to their association. If the association is complete, design is complete as well. 

OO implementation using OO language: In the stage, the design is implemented using object oriented languages like Java, C++ etc,.

• Role of UML in OO Design

Our Online UML assignment help Australia experts point out that the relation between UML and OO design is very important to understand. The OO design is transformed into UML diagrams when it is required. The output of OO analysis and design is transferred to input of UML diagrams.
