CONTENTS OF THIS CHAPTER

This chapter covers the following topics:

  • what is modelling?
  • rationale for modelling;
  • the need for multiple models and views;
  • commonly used modelling techniques;
  • cross-referencing models and views;
  • documentation and specification;
  • references and further reading.

There are many modelling notations and frameworks in use and this chapter does not attempt to describe them in detail. It does, however, discuss some theoretical issues of modelling, with examples, that will allow readers to understand and assess alternative approaches with the aim of being able to select and apply models appropriate to the problem presented by the specific solution requirements.
