Object oriented computer programming and design methodology has become popular as a way of modeling and solving many programming problems. Traditionally, the implementation of such systems has been performed using an object oriented programming language such as C++. Those skilled in the art know that object oriented programming languages share at least five unique and defining concepts or notions. These concepts, which are discussed fully in the relevant literature pertaining to object oriented programming, are known as: CLASSES, OBJECTS; INHERITANCE; POLYMORPHISM, and ENCAPSULATION. Objects communicate with one another via "message passing." A "message" is texts string such as "redraw you". When an object receives a message, a corresponding class method is executed. It is well-known that in object oriented programming, different objects of an object oriented programming language will respond to messages differently.

Shift from top-down to OOP could be called going from fourth to fifth generation, in that what it enables programmers to do better or more conveniently than they could with the more primitive languages resembles what the higher generation languages enabled them to do over the lower generation ones. OOP, however, is a paradigm shift as significant as that from first to second or, arguably, from second to third -- but far more radical than the from third to fourth. Of course, it is impossible to quantify this, but in terms of ease of programming and what OOP enables, it might be fair to say the leap from fourth-generation languages to OOP, especially what OOP has now become, can be likened to the span between binary code and BASIC. OOP supercharges the program environment.

At each generational jump from binary to assembly language, to third-generation, to fourth-generation, the leap made programming easier and enabled more complex tasks by adding layers around the central core of binary code and its next outer layer, assembly. All programming languages including the advanced OOP iterations that are out now, are parsed down to binary to be executed by the computer. It's all fundamentally the same.

OOP packaged the laborious and error-prone systems of calling subroutines with variable parameters we used in the old days with a very slick interface, an envelope of error-checking and ease of use.

Object Oriented Programming organizes programming logic around objects instead of processes (as is the case with non-OOP). Some widely used third generation, object-oriented programming languages include C++, Java, and Smalltalk. In OOP, data, and the processes that can be performed on the data, are combined into an object. In addition, objects with similar characteristics may be combined into something called a class. So when an OOP programmer creates a class and wants to categorize certain files they are able to create a sub-class. Sub-classes inherit all the characteristics and processes from the original class file that it is derived from. Inheritance is one of the most powerful features of OOP. Once a programmer creates the subclass, he can add to or change the characteristics and processes to meet the precise needs of the subclass. An example of an OOP is Microsoft Office Suite products (Word, Excel, PowerPoint, Access). First Generation Programming is a machine language. It only understands zeros and ones, so we say machine languages are binary. Second Generation Programming is also called assembly languages; it uses simple words in place of zeroes and ones. The programmer associates each assembly language statement with a specific machine language command. Third Generation Programming uses source codes that could then convert into machine language. A special computer program, called a compiler, would handle the conversion. A compiler is a computer program that translates a specific third generation language (3GL) into machine language. Forth Generation Programming languages are closer to natural language. People who have little or no programming skills can use them to write simple programs. One example of a 4GL is structured query language (SQL). Structured query language is a standard language for manipulating databases. Users can write simple SQL programs to create a database, enter data, retrieve data, and delete data. How are they similar? All programming languages still go back to the First Generation Programming language, Each generation has become more advance, with better tools and features. But each language resorts to machine language.
