Programming is a journey between the real world and a computer. Unfortunately, what’s in the real world is just about as far from the insides of a computer as you can get.
The real-world is a complex place and to make the journey, we should be able to represent it within the computer.
In the real world of banking we must be able to represent customers, staff, cash, stocks, interest, insurance, and the like.
In the real world of civil engineering projects, we must be able to represent the bricks and mortar, arches, building stresses, blue prints, and engineers.
In the real world of universities, we must be able to represent students, courses, examinations, associate lecturers, academic.
