UML 2.0 in Action: A project-based tutorial

Overview of this book

Most books about UML describe it almost in its entirety. Inevitably you're left with only a superficial knowledge of the range of UML elements, without a deep and intuitive understanding of how to apply UML as a whole to real world design problems. This book doesn't set out to cover all of UML, but instead pulls together those parts of UML with immediate practical relevance and presents them as part of a coherent process for using UML in your actual development projects.This book is designed to be read while you work on a real project. After an initial review of the essentials of UML and the design process, it begins with the modeling of a business system and its business processes, in this case an airport. Then the IT system intended to serve that business process is described and analysed. Finally the integration of the system into the production environment is covered in detail. The book can be used in two ways: it can be read through as a thorough grounding in how UML really works in practice; in addition it can be used as stand alone guide to that particular aspect of your own project. Both result in an intuitive understanding of how to actually use UML.

2.4 The Models of our Case Study


In our case study we construct three models of different systems:

  1. The model of the business system describes passenger services, meaning the business surroundings of the IT system. It deals with business processes, passengers, business partners, employees, etc. We discuss this model in Chapter 3, Modeling Business Systems.

  2. The model of the IT system explains the IT system that was built for passenger services. The model of the passenger service business system serves as the foundation for the model of the IT system. We discuss this model in Chapter 4, Modeling IT Systems.

  3. The model of system integration describes integration into the environment, especially gateways to the outside world. Here also, the model of the passenger service business system serves as the foundation. This model is discussed in Chapter 5, Modeling for System Integration:
