Object Oriented System (3rd sem)

What is OOS-

A software model or system designed using object oriented approach is basically a object oriented system

Object Oriented Approach

In software development, we generally uses either a function oriented approach or Object oriented Approach.

Function oriented approach is basically what you have done or observed while programming in C.

Our overall system is divided into functions that performs various operation on data.Function are the basic element of our system.

For eg. While you are going to build a software system for Library management.Using Function oriented approach while designing the system we try to identify the function making up the system.Some of the possible function might be-"returning of books by student to librarian","issuing of books","putting books on shelf" etc.

So while designing the actual system , we consider these system for carrying out the manipulation of data and providing the desired result.

Object Oriented Approach is something which is very easy to understand and implement. Actully all real world Problems can be viewed as object oriented.

Its a real world programming concept.

In this approach of design,we considers the object making up the system,and objects has the data and related function that can be used by it.

So take a real world problem for understanding it-

If you want to build a system for library management then the possible objects that make up the system are "student","librarian","shelf" etc.All these object has data(attributes of object) and methods(operations performed on data) with in them.
