About the examples

Examples from the book

These are the examples used in the Domain Storytelling book written by Stefan Hofer and Henning Schwentner:

  • Alphorn car leasing: The stories named 1 and 1a show on a coarse-grained level how this leasing company operates. The stories with payment, offering, and risk assessment in their name show subdomains of Alphorn in more detail.
  • Metropolis arthouse cinema: The manager of this small, old-fashioned cinema wants to introduce an app for movie-goers.
  • Opening stories: Several chapter in the book open with a story that explains the content of the chapter. Domain stories describing Domain Storytelling—that's how we have fun!
  • Travel: Three stories about traveling. They illustrate that Domain Storytelling works in different natural languages, e.g., German, Chinese, and Farsi.

More examples

  • Organizing an investment conference: This story was modeled with a real domain expert in a meetup. Watch the recording of the session on Youtube!
  • External authentication provider: This story illustrates that domain stories can be about technical processes too. It is an anonymized real-world example of a web app that uses an external provider to manage user accounts.
