Introduction

Abstract

Object-oriented programming has opened a great many perspectives on the concept of software and has been hailed as part of the solution to the so-called “software crisis”. It has given the possibility that software components can be constructed and reused with considerably more credibility. There are now many case studies in which the reuse of object-oriented components has been made and analysed. Object-oriented programming relates the programming activity to that of modelling or simulation; objects are identified by a correspondence with the objects found in the application area of the program and are used to model those domain operations. Object-oriented programming also opens the prospect of more flexible software that is able to respond dynamically to the needs of the application at runtime.
