I am a freelancer. I have developed Five Software Applications (windows based) with the help of VB.NET. I know that by default all the .vb files create there own Classes and .NET Environment itself create several classes on its own. But in any of my Projects I have not created a SINGLE Class of my own.
In this kind of scenario what I felt that I am using OBJECT BASED APPROACH rather than OBJECT ORIENTED APPROACH. I have developed projects like Student Management System, Accounts Management System for Trading Business etc. My next project is LIBRARY MANAGEMENT SYSTEM. I want to do my next project in Object Oriented approach.
I will be very much helpful if any body helps me in this regard. I just want to know the ways of Object Oriented Approach keeping in view of LIBRARY MANAGEMENT SYSTEM. What are the ways from where I shouls start ?????

It's not hard.

Write down your problem, do "noun" analysis.  See http://www.objectmentor.com/publications/casestud.pdf [PDF link]  These nouns probably suggests classes / objects in the final system.

Identity relationships between the nouns.  For example, you have a rental which is either an issue / return, so this suggests to me that an issue is a rental, and a return is a rental, therefore I'd consider an inheritance relationship between the two.  A person has a number of rentals which sounds like another relationship to me.

Identity the salient data that needs to be recorded.  Group related data together.  Ensure data is not repeated.  See http://en.wikipedia.org/wiki/Database_normalization [Wikipedia].

Draw some UML, find out what a Use Case is, see http://en.wikipedia.org/wiki/Use_Case [Wikipedia].  Draw some class diagrams, see http://www.agilemodeling.com/artifacts/classDiagram.htm [Agile Modeling].

Once you have your diagrams, move to concretise them in VB.NET definitions.
