11 Case Study
This chapter will bring together all of the previous chapters showing how these essential concepts work in practise through
one example case study.
Objectives
By the end of this chapter you will see
• how a problem description is turned into a UML model (as described in Chapter 6)• several example of UML diagrams (as described in Chapter 2)• an example of the use of inheritance and method overriding (as described in Chapter 3)• an example of polymorphism and see how this enables programs to be extended simply (as described in
Chapter 4)• an example of how generic collections can be effectively used, in particular you will see an example of the
use of a set and a dictionary (as described in Chapter 7)• an example of these collections can be stored in files very simply using the process of serialization (as
described in Chapter 7)• examples of exceptions and exception handling (chapter 9)• examples of automated unit testing (chapter 10).• finally you will see the use of the automatic documentation tool (as described in Chapter 8).The complete working application, developed as described throughout this chapter, is available to download for free as
compressed file. This file can be unzipped and the project loaded into Visual Studio 2010.
The express edition of Visual Studio 2010 is available for free download from http://www.microsoft.com/express/Downloads
though this does not include support for the unit testing.
The automatic documentation created to describe the system is available as a set of web pages and can therefore be viewed
by any web browser.
