Object Oriented Programming

Most modern software programs are built on the concept of Object Oriented Programming (OOP) .

The concept was first fully introduced in a radically new programming language, Smalltalk that was developed by a team lead by Alan Kay at Xerox's research lab, PARC .

The idea of OOP was that lines of code and data sets could be defined as self-contained ‘objects’. As such, they could be utilized multiple times by multiple programs by simply referring to them by name.

Kay developed this concept based on a software language called Simula .

Ward Cunningham, Kent Beck and others integrating the concept of Pattern Languages into OOP and used it as the foundation for the new agile experience they were exploring.
