Object Oriented Applications: Integration, Quality Assurance, and Deployment

Abstract: The article reviewed the founding principles of object oriented programming (OOP), unlike procedural programs, classes written in OOP do not normally provide access to the private instance variables to the external accessors. The advantages and disadvantages of OOP are discussed. Design patterns as described below, is a tried tested solution for a well-known problem. Design patterns do exists in the outside world and that is where they are applied to software development in general and OOP in specific. The best way to see design patterns at work is to design an application using them. The section for the design pattern does just that. While encapsulation is very important in OOP, high reusability through inheritance and composition is another great attraction of OOP. The section for reusability in OOP discusses that aspect. Finally the last section touches upon the relationship between UML and Object Oriented Programming
