This text uses an object-oriented approach based on Rumbaugh's Object Modelling Techniques, which is one of the major object-oriented methods for software development. Its main aim is to show how to structure and build an application from first principles. The book covers the complete software development lifecycle and includes real-life code examples, exercises and solutions. C++ features are covered, including templates and exception handling. A section is included on the classification of class associations and relationships with subsequent possible mappings into C++.
