Example Case Study: A Newspaper
To illustrate these four interaction patterns and their implementation options we will use a simple example based on a newspaper business (Figure 11-6). In this example there are three participants: the newspaper itself, a party acting as a news source, and a customer of the newspaper.
Figure 11-6 Newspaper Example Architecture Pattern
We will examine four use cases (processes) involving these participants:
- The news source delivering a news tip to the newspaper (In-Only)
- The customer subscribing to the newspaper (In-Out)
- The newspaper sending the news electronically to the customer (Out-Only)
- The newspaper sending an offer to the customer that requires a response (Out-In)
