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.

IT systems and people within the business system are responsible for offering the goods and services of the business system. With that, we leave the environment of the business system and enter the black box. From now on, we do care about whether the processing within the business system occurs manually or is IT supported, whether employees of the organization have to fill out two or twenty forms, and whether suppliers are needed.

The following diagrams illustrate the internal view:

  • Package diagrams describe the organization units in the form of packages.

  • Class diagrams describe the connections and relationships between co-workers and business objects.

  • Activity diagrams describe the business processes within the business system. The subjects of the description are the goods and services that are provided by internal business...
