Question

what is the essence of the object oriented analysis and design approach with UML diagramming tools

Answer 1

Essence of Object Oriented Analysis and UML Diagram:

Take a Problem and technical solution in terms of objects (Items, Concepts and Models), so for solving the problem following things are important:

• Analysis: Analysis and brief the Concepts(objects ) in the problem statement.

       Example : Some Concepts in the Car information system: Wheel, Brakes , etc

• Design : Design is way in which the objects or the Analysis you did, will be in implemented in the object oriented programming language.
• Object oriented  Programming : Designed components are implemented using the Language example JAVA .

Note Why We need Analysis:

-> To Understand the Problem: example Construction of the Car.
-> To understand the use cases of that problem . example : Driving.
-> To Make the Problem easy to solve (breaking problem into bits so that we can solve it step by step in the planned way).
UML Diagram tool :
Example : UML diagram maker(Tool).

-> UML diagram is one way of presenting the design/implementation that can we done to solve the problem.
   UML Diagram contains some shapes for example:
   1) Rectangles : Which represents the classes that can be used for implementation for the problem.
       a) Inside rectangle, we can mention names of attributes/Methods which can be used for implementation.
   2) Arrow : To show the Association/Relation of the classes which are used in the design.
           a) on the arrows we can also define what kind of the relationship it is developing.
               -> Parent child relationship(Inheritance.)
   So, for making UML diagrams, we have various tool in the market which is use to create the flowchart also known as UML diagram for the Problems for which we can design to solve it.
