What is object orientation? Why is it becoming important and relevant in software development? How is it improving the life of software developers? Is it a buzzword? Many such questions come into our mind whenever we think about object orientation of software engineering. Companies are releasing the object oriented versions of existing software products. Customers are also expecting object oriented software solutions. Many developers are of the view that structural programming, modular design concepts and conventional development approaches are old fashioned activities and may not be able to handle today's challenges. They may also feel that real world situations are effectively handled by object oriented concepts using modeling in order to understand them clearly. Object oriented modeling may improve the quality of the SRS document, the SDD document and may help us to produce good quality maintainable software. The software developed using object orientation may require a different set of testing techniques, although few existing concepts may also be applicable with some modifications.

WHAT IS OBJECT ORIENTATION?

We may model real world situations using object oriented concepts. Suppose we want to send a book to our teacher who does not stay in the same city, we cannot go to his house for delivery of the book because he stays in a city which is 500 km away from our city. As we all know, sending a book is not a difficult task.
