Object Oriented Design and Programming is essential for any organization that wants to quickly model existing business rules and implment those rules.
Object Oriented Design is the concept that forces programmers to plan out their code in order to have a better flowing program.
The origins of object oriented design is debated, but the first languages that supported included it wereSimula and SmallTalk.
The term did not become popular until Grady Booch wrote the first paper titled Object-Oriented Design, in 1982.
Object Oriented Design is defined as a programming language that has 5 conceptual tools to aid the programmer. These programs are often more readable than non-object oriented programs, and debugging becomes easier with locality.
