Subsystem Stereotype Sample

The subsystem stereotype sample demonstrates how subsystems collaborate to make up a larger system. The sample below illustrates a bookstore system and the smaller subsystems that make up the total system.

Figure 97 Subsystem Stereotype Sample

The four subsystems in the subsystem sample together make up all the functionality of the Bookstore Enterprise System. Note that through the <<include>> relationships, each subsystem provides a certain piece of the Bookstore system functionality.

Instead of going into separate subsystems, a user of the Bookstore Enterprise System can verify stock in the Warehouse Subsystem or check the status of a shipped book in the Mailing Subsystem, for example. All subsystems make up a much larger system. Each stereotyped package subsystem is just a means of organizing model elements and diagrams together.
