Constructing an Object Oriented System

Abstract

This chapter takes you through the design of a simple object oriented system. It does not concern itself with implementation issues nor with the details of any particular language. Instead, the aim of this chapter is to illustrate how the concepts described in the last two chapters can be used to construct a software system. In the remainder of the chapter we describe the application to be constructed. We then consider where to start looking for objects and from there, what the objects should do and how they should do it. We conclude by discussing issues such as class inheritance and answer questions such as “where is the structure of the program?”.
