Introduction

Alice: ``Would you tell me, please, which way I ought to walk from here?''
``That depends a good deal on where you want to get to'', said the Cat.
``I don't much care where -'', said Alice.
``Then it doesn't matter which way you walk,'' said the Cat.
``- so long as I get somewhere,'' Alice added as an explanation.
``Oh, you're sure to do that,'' said the Cat, ``if you only walk long enough.''
Lewis Carrol, "Alice's Adventures in Wonderland''.

4The object-oriented paradigm can be applied with the goal of reducing design complexity and increasing design consistency. In this dissertation we show that by applying this design and implementation technique we can also address other important issues: high efficiency and scalable system behaviour.
